8:50AM - 9:40AM        Communication Technology Roadmap
                       Jurgen Michel Massachusetts Institute of Technology, USA

Abstract: In 2005, the Communication Technology Roadmap (CTR) I Report correctly noted a
shift in technology from classic telephonic communications infrastructure to data-centric
packet-switched communications. The report also forecast the impending integration of photonic
circuit elements within standard electronics circuits and noted the inability of any single
commercial entity to resolve these issues independently. We will present the findings from the
most recent report, CTR II. In this report, an even greater change in direction is observed as
Information Technology is reaching limits in its ability to scale to greater capacity and
functionality. The emerging barriers to the scaling of information technology are power efficiency,
bandwidth density, and cost. By 2018, the energy utilized by Internet Protocol (IP) traffic is
predicted to exceed 10% of total electrical power generation in developed countries. Parallelism in
computational architecture is the accepted solution to power efficiency of information processing,
but bandwidth density bottlenecks are occurring throughout the interconnection hierarchy from
cloud networks to chip-to-chip interconnects. We will discuss the opportunities for optical data
transmission and photonic integration in telecommunication, computation, imaging, and learning.

                         Si CMOS Platform
                         Kazumi Wada Tokyo University, Japan

Abstract: It is clear that wavelength division multiplexing (WDM) on a chip to enable orders of
magnitudes higher performance computing and communication. The biggest challenge is heat
penalty in circuit operation, i.e., on-chip thermal fluctuation leading malfunctioning WDM in
terms of wavelength fluctuation. Thus various attempts have been reported enable on-chip WDM
without huge success. To breakthrough this issue we have proposed Si MEMS photonics to lock
the wavelength in terms of refractive indices and bandgap dependence on strain. The present paper
describes the current status of the Si MEMS photonics and discusses the future prospectives.

14:20PM -15:10PM        A Silicon Photonics Platform with Heterogeneous III-V Integration
                        Wim Bogaerts Ghent University, Belgium

Abstract: We will present an overview of the work by Ghent University and imec on a
multipurpose photonic platform based on silicon technology with heterogeneous integration of
III-V materials. Silicon photonics is widely considered to be the most promising technology to
realize a high-performance, low-cost and high-volume photonic platform that can enable complex
VLSI photonic functionality. One of the key enablers for silicon photonics is the possibility
leverage existing silicon processing technology. Silicon as a material is exceptionally suited for
compact passive waveguide circuits, but for light detection, and especially generation, III-V
materials are by far superior. Heterogeneous integration of III-V materials on silicon photonic
circuits has already been demonstrated in working lasers and efficient photodetectors. We will
discuss the recent progress in adhesive III-V-on-silicon bonding technology, with working lasers,
microlasers and different types of photodetectors, and how these devices can be used for different
purposes. III-V integration can only be successful if integrated in a fully functional silicon
photonics platform. III-V materials are typically not used in a silicon process environment. To
accommodate the III-V materials inside a silicon process flow, careful considerations have to be
made for contamination and temperature budget. Imec is constructing a full silicon photonics
platform which not only integrates passive silicon photonics, but also modulators, germanium
photodetectors, thermal tuning, III-V integration and 3-D integration with electronics

                         High Efficiency Solar Cells
                         Ching Ping Wong Georgia Institute of Technology, USA

Abstract: Solar energy is green and environmentally friendly energy sources compared to
traditional energy sources (fossil fuels, nuclear, coals, etc.). It is indispensable in energy
production in spacecrafts and satellites, and is becoming more widely used in microelectronics and
photonics. Optical and electrical losses are primary factors that influence photovoltaic conversion
efficiency. In particular, the optical loss attributed to the reflection loss of the incoming light. By
incorporating a novel nano surface technology with multiple internal reflections, low surface
reflection and high light -absorption are achieved. Therefore the efficiency of photovoltaic devices
can be significantly enhanced. One-dimensional semiconductor nanowires offer the unique
advantages such as large surface area, high optical absorption across a broad spectrum and high
charge collection efficiency. ZnO nanowires, an outstanding member of the family of one
dimensional nano structures, have many applications for fabricating electronic and optoelectronic
devices. ZnO nanowire is an attractive dielectric antireflection coating material for PV
applications due to its high transparency, appropriate refractive index (n = 2), and its capability to
form a textured coating via anisotropic growth. It was reported that ZnO nanowires display the
reflection suppression at broadband wavelengths range, and have been widely used in
dye-sensitized solar cells as well. In our study, we grew ZnO nanowires on a textured Si surface
for superhydrophobic, low light reflection, and high efficiency solar cells. In our study, the
pyramidal silicon structures were made by etching the silicon wafer with KOH, water, and
isopropyl alcohol at elevated temperature. Then ZnO nanowires were grown on the pyramids
using a hydrothermal decomposition method from a ZnO seed layer. This ZnO nanowires
formation process is cost-effective. The superhydrophobicity on the top ZnO nanowire surfaces
was achieved by using perfluorooctyl trichlorosilane. The weight reflectance (WR) was calculated
by normalizing the hemispherical reflectance spectrum (300-1200 nm) measured. It was found
that the ZnO nanowire serves as an antireflective layer similar to a conventional SiN passivation
and such a structure helps further reduce the reflectance. As a result, a weighted global reflectance
of 6.5% was achieved. We further fabricated, characterized and analyzed the screen-printed solar
cells of ZnO nanowires. Then cell performance was characterized by light I-V as well as internal
quantum efficiency (IQE) measurements for the short-wavelength response. The final efficiency of
our nanostructured solar cell device, the experimental details and surface characterization results
are presented in this paper.

Abstract: The need for increased IO bandwidth in and around the CPU in many different
computer systems has stimulated the research into optical interconnects for many years. Intel has
been pursuing Silicon Photonics, a technology which creates optical components from a silicon
substrate, as a candidate for these applications and has developed a series of silicon based
photonic building blocks. Here we report on a silicon photonics based WDM link demonstrating
all the key technologies required to create a viable optical link for system integration. This
4-channel CWDM integrated silicon photonics link was designed to operate at a line rate of
10Gbps per channel. When over-clocked to operate at 12.5Gbps per channel, we succeeded in
demonstrating a 50Gbps aggregate bandwidth silicon photonics link.

                        Kunji Chen Nanjing University, China

Abstract: Similar to the three dimension (3D) quantization of electric states in semiconductor
quantum dots (QD), in the 3D optical microcavity structures the discretization of photonic states
can also be observed. Based on this concept, the 3D optical microcavity may be termed as
photonic QDs. In this paper we proposed an approach to build Si based 3D optical microcavity, in
which photons were confined by Bragg reflectors in all dimensions instead of the lateral
confinement by using total internal reflection. Size-dependent photonic energy modes were
observed when the lateral size is changed from 4 μm to 1 μm. With decreasing lateral size the
modes shift to higher energies, and the splitting between the modes increases. The observed
discrete optical eigenmodes show a quantitative agreement with numerical calculations based on
model of quantized photonic states in the photonic QDs. Based on two coupled 3D photonic QDs
structure, two main bands of discrete optical eigenmodes which similar to the bonding and
anti-bonding modes in the molecule energy spectrum have been observed. The energy positions of
modes are dependent on the lateral size and the coupling distance. This study could be stimulation
for both basic research and application in photon manipulation of silicon photonics.

10:30AM-11:20AM        Phosphorus and Boron Doping of Silicon Nanocrystals
                       Deren Yang Zhejiang University, China

Abstract:Research on silicon (Si) nanocrystals (NCs) is critical to the next-generation Si
technologies for nanoelectronics, optoelectronics and photovoltaics. In the past two decades both
the effect of NC size and that of states introduced by surface defects and impurities on the
properties of Si NCs have been carefully studied. Recently, the focus has shifted to intentional
modification of NC composition as an additional means of improving the properties of Si NCs.
We will introduce recent work on the doping of Si NCs with boron (B) and phosphorus (P). Our ab
initio calculations show that the most probable locations of dopants are actually at the surface of
Si NCs, since the formation energies of B and P are the lowest when they substitute or passivate Si
atoms at the NC surface. This signifies the difficulty of tuning the electrical conductivity of Si
NCs by doping, which inherently requires the incorporation of dopant atoms into the lattice sites
inside Si NCs. Experimental work shows significant loss of P after removing the oxide layer of
oxidized P-doped Si NCs, consistent with the above-mentioned theoretical prediction that P is the
most likely resides at the NC surface. In contrast, the concentration of B increases after the oxide
layer of oxidized B-doped Si NCs is removed. The underlying mechanism is currently investigated.
Our calculations explain the doping-induced changes in the light emission from Si NCs. The
infrared absorption of P-doped Si NCs actually originates from transitions involving
doping-induced deep energy levels, rather than free carriers. We also explain the absence of the
infrared absorption of B-doped Si NCs.

Abstract: In the recent research of organic optoelectronic material developments, more and more
attention has been paid to introduce silicon, which is a widely used element in inorganic
optoelectronics, into the organic molecular systems to modify and improve the desired functional
materials. Silicon-containing π-electron systems are interesting organic functional materials
because of their unique interaction between the π*-orbital of the π-modules and the σ-orbital of
the exocylic silicon-carbon bonds, which effectively tunes the molecular and electronic structures
and properties of the organic materials. In this presentation, I will review the applications of
silicon in the optoelectronic organic systems which are closely related to our work, considering
the future development directions of this important research field. Silanes, silicon-inserted organic
systems, and silicon-substituted π-electron molecules will be briefly introduced and discussed. I
focus on the silicon-bridged π-system, which I think is the best way to introduce silicon atom into
the π-conjugated molecules. I believe the marriage of silicon which is the star element in inorganic
optoelectronics with the π-conjugated organic systems opens a door for both structural and
functional modifications and improvements of the organic molecules, and the forthcoming in
depth investigations on this silicon-containing organic material will eventually put the organic
electronics into reality.

Abstract:We report on the development of all-silicon platforms for label-free biosensing. The
biosensors consist of photonic crystal (PhC) microcavities built in either porous silicon [1,2] or
silicon-on-insulator [3-6]. The present devices are functionalized to capture the appropriate targets
with a negligible false positive response. Both the 1-D and 2-D platforms allow for the detection
of minute amounts of biological matter but the 2-D PhC microcavities also make single virus
detection possible [4]. We will discuss the design and fabrication of PhC microcavities, show how
they can work as biosensors and illustrate their performance with multiple examples.

                        David Citrin Georgia Institute of Technology, USA

Abstract:Pendry proposed using metal films to achieve negative-index effects—a proposal that
relies on local and macroscopic electrodynamics whereby the metal film is characterized by a
(scalar) index of refraction. In this talk we show how such a view must be abandoned for
nanostructures composed of noble-metal nanoparticles. Due to the strong polarization dependence
of surface-plasmon polaritons in metal nanoparticle chains (1D) and arrays (2D) on dielectric
substrates, such as silicon, different polarizations of an incident optical field suffer different
amplitude and wavefront modulation. This leads to different ―images‖ for spatial Fourier
components of the incident field polarized (principally) parallel or perpendicular to the in-plane
wavevector. We discuss effects due to 1D nanoparticle chains for possible imaging applications
in Si-photonic waveguides and for optical vector beam formation by 2D nanoparticle arrays. In
particular we discuss the use of such structures for the formation of optical vector beams.

16:20PM - 17:10PM        Surface Plasmon Assisted Emission Enhancement for Silicon
                         Yidong Huang Tsinghua University, China

Abstract: Silicon nanocrystals show intense visible luminescence at room temperature due to
quantum confinement effect and surface state assisted radiative recombination. Observation of
light amplification in silicon nanocrystals indicates their potential optoelectronic applications.
However, dominating nonradiative recombination induces low internal quantum efficiency (QE).
According to Fermi’s golden rule, large density of states (DOS) can enhance spontaneous
emission (SE), and then improve the internal QE. It is known that the metal surface plasmon (SP)
have been used to enhance the SE of GaN/InGaN quantum wells and ZnO, because specific
dispersion relationship of SP causes a large DOS in the blue or ultra violet (UV) range, near the SP
resonance frequency. Effective enhancement needs that the SP resonance energy coincides with
the light emission energy, which was demonstrated by K. Okamoto et al. Unfortunately, unless
silicon quantum dots were with very small size and few surface states, the central emission
energies are usually much lower than the resonance energy of the commonly used metal
surface-plasmon waveguides. In this report, we will discuss a kind of metal-rich cermet to lower
the plasmon energy by doping dielectric into metals. By properly choosing the component of the
cermet, the resonance energy can be engineered to match the central emission energies of
nanostructure silicon. To obtain further larger region enhancement, we proposed doublelayer
surface-plasmon strucutre, which shows potential in developing high efficiency electric pump
silicon based light sources. Besides, the spontaneous emission (SE) enhancement due to SPP band
gap effect on metallic grating was evaluated. Within the range of Silicon nanocrystals (Si-NC)
luminescence (  =1.9eV~1.6eV), the calculated maximum Purcell Factors for Au/Ag/Al-Si3N4

not only Au but also Ag and Al, which SPP resonance frequencies are rather higher, can be
adopted to enhance the SE from Si-NCs.

Abstract: Introduction of MOSFET scaling over the years is given and today’s challenges,
including the issues of power consumption, process parameter variation, short-channel effect etc.,
are described. The importance of strained Si methods for enhancing MOSFET performance, such
as Dual Stress Liner Technique, Stress Proximate Technique, and Replacement Gate Technique,
are discussed. Particular attention is given to the process variations induced by IC manufacturing.
New device structures, which combine the merits of planar MOSFET and FinFet, are presented and
considered as possible solutions for 16nm CMOS technology and beyond.

                            Process R&D Center, the Institute of Microelectronics of Chinese
                            Academy of Sciences, and is responsible for advanced CMOS
                            technology research. Professor Zhu obtained his B.S. in 1982 in physics
                            at the University of Science and Technology of China, Anhui, China,
                            and his Ph.D in 1988 in physics at the Beijing Normal University,
                            Beijing, China. He worked at Argonne National Laboratory in
                            1990-1992, University of Illinois at Urbana-Champaign in 1992-1996,
                            Digital Equipment Corporation in 1996-1998, Intel in 1998-2000, and
IBM in 2000-2009. He joined the Institute of Microelectronics of Chinese Academy of Sciences
in 2009. Professor Zhu is co-inventor of Dual Stress Liner Technique and Stress Proximate
Technique, which have been widely used to enhance CMOS performance. He is also co-inventor
to use recessing gate to enhance stress in the channel of a strained MOSFET, which has been
applied, as a key technique, to advanced high-k metal gate CMOS products. He is one of pioneer
researchers of molecular-dynamics-simulation and theoretical modeling of nano-particle
interaction. He first applied molecular dynamics simulation to study of nano-particle sintering and
discovered super-fast sintering (within a few tens pico-second) and relatively rotating of
nano-particles. He developed a model for Ge and Sb diffusion in Si1-xGex system and, for the
first time, excellent agreement to experimental data was achieved in a large range of Ge fractions
and annealing temperatures. Professor Zhu has 130 issued US patents,more than 100 US pending
patents and over 40 technical papers. He was one of four IBM Corporate Leading Inventors
(2007) and an IBM Master Inventor (2008).
