                      Future Trends

 Increasing number of end users and individual sources of
  information such as a PC-based servers generate information in
  excess of 10 Gb/s per user (modern PCs have optical I/O)
 Future applications require end-user to end-user communications
  (3D holographic telepresence, high definition. display arrays, etc.)
 End users connecting to Data Centers (Google, Facebook, etc.)
 Scaling to high bandwidths requires use of optics in
  communication and interconnections (e.g., optics is needed for
  >100 m, or speeds over 10 Gb/s)

New transformational optical technologies are needed that will
  create new functionalities at low cost

        CIAN Vision/Broader Impact

CIAN vision is to enable high bandwidth
networked services at low cost with high
energy efficiency.

The broader impact of CIAN research include
• Education (multi-media delivery, e-learning)
• Healthcare (telemedicine)
• Cyber presence and energy efficiency (telecommuting/telepresence)
• Enable new business opportunities in entertainment, etc.

 Mission: Technical Formulation of
            CIAN Vision
CIAN will create transformative optoelectronic technologies for
  optimizing complex networked systems that are:
 Reconfigurable, more intelligent
    topologies for multiple dynamically varying application loads and
     services
 Scalable
 Transparent (protocol, modulation format, less OEO’s etc.)

The optimization attributes include:
      Energy
      QoS
      Bandwidth
      Fault tolerance
      Adaptation speed
      Cost
         Manufacturability (CapEx)
         Operation cost (OpEx)

 Impact of CIAN Box in Future Aggregation
                Networks
Key metrics:
• Decrease energy consumption from current state-of-the-art working with
GreenTouch by 100x-1000x
• Enable faster, fine granularity (per packet) data switching in the optical
  domain: <100 nanosecond – today state of art is 100s ms
• Increase bandwidth utilization to >90%

The CIAN box is able to route data on per-packet basis in the optical domain. It can do this
because it has the cross-layer capabilities, we can keep data in the optical domain and know its
signal quality (QoT) without having to convert to the electrical domain. By keeping data more in
the optical domain we can aim to reduce greatly the energy consumption (this is supported by
data from our work with GreenTouch). By switching at the packet rate and knowing the QoT on
a per-packet basis we can combine all types of heterogeneous traffic into the optical streams,
thus increasing the bandwidth utilization. This can provide users very high bandwidths in a cost
effective way since they get it only for the period of time they are transmitting packets and are
efficiently sharing the channel with all types of other users that may need different QoS.

 Designed and implemented hybrid optical/electrical switching
  DC system and provided top-down technology drive.
 World record speed in implementing sorting algorithm.
 First CIAN Box is under construction at Columbia satellite
  testbed and an early version will be inserted in TOAN before
  end of 2011.
 Quality-of-Service-Aware Video Transmission over a Cross-
  Layer-Controlled Metro-Scale.
 Demonstrated Holographic Telepresence.
 Demonstrated Silicon Photonic Integrated Pulse Compressor,
  and a 1x4 WDM add/drop filter.
 Demonstrated Nanolasers integrated with silicon.
 Published six Nature articles and a total of 75 publications.

     Challenges and Bottlenecks of
           Current Networks
 Trickle down of the bandwidth to the end users even with
  Tb/s “core”: access/aggregation bottleneck.

 The current networks do not provide high bandwidths to end
  users and Data Centers
    Cost prohibitive
    No “intelligence” in switching, routing and no dynamic
     bandwidth allocation
    No control over the optical physical layer
 The current networks are energy hungry
    E.g., Data centers are typically built near energy
     generation sites
