					Optical Computing in IT
Optical computing means performing computations, operations, storage and
transmission of data using light instead of electricity. Instead of
silicon chips optical computer uses organic polymers like phthalocyanine
and polydiacetylene.Optical technology promises massive upgrades in the
efficiency and speed of computers, as well as significant shrinkage in
their size and cost. An optical desktop computer is capable of processing
data up to 1,00,000 times faster than current models.
Advantages
- Optical computing are cheaper or more powerful than conventional
computers. - Within one data path several data sets can be transmitted
parallel at the same time using different wavelengths or polarizations.
data paths are able to cross each other without interference. - The
superior velocity of light allow extreme processing speeds. - Optical
computers are said to run much faster than electronic computers
Disadvantages
- The development of its price is still expensive - Optical components
can be build small and compact but not really miniaturized - Optical
computers may use a different architecture. So these programs cannot use
the full optical computers - High-tech factory costs several millions up
to billions of dollars to be built
Comparision of Optical computing with conventional computers
Optical computing
- Data paths are able to cross each other without interference - Based on
two dimensions - High performance - Bottleneck could disappear - Less
heat is released - Less noise - Change the shape and layout - The
distance of communication does not matter - Long-range communication is
possible. the data rate is very high and there is no crosstalk
conventional computers
- Crossed data paths are not possible - Based on three dimensions -
Performance lesser than optical computing - Bottleneck could appear -
Produce heat to a greater or lesser extent - A lot of noise. developed
fans to reduce noise - Built as a rectangular box (desktop) or as a
laptop - Communication depends on the distance - Longer distances
decrease of the practical transfer rate
Features
- Wireless Optical Mouse - The ultimate speed is the speed of light. -
Massaging your hand by infrared ray - Quick and stable temperature (at
451) for warming your hand - Safety material for avoiding damaging the
component of mouse - High precision option - Plug and play, no-driver
required - Scroll without scrollbars - Optical tracking engine -
Comfortable shape - low-consumption devices The mouse is designed to be
used by younger children and features a smaller form factor that allows
for an easier grip. It also features a colorful design that will make
your child more interested in using a computer. - The mouse itself is
rated for up to 1 million clicks. The mouse features an 800 dpi o ptical
tracking interface. Optical tracking is much more precise than a
mechanical ball mouse, and is also less prone to mechanical failure.
Past research
Existing silicon technology would represent a potentially less expensive
and more feasible way to mass-produce future-generation devices that
would use both electrons and photons to process information, rather than
just electrons as has been the case in the past.
Less than one year ago, created laser light from electrical current on
silicon by placing a layer of the silicon.
Ongoing research
This research builds upon the development of the silicon laser. Computer
technology now depends on silicon electronics for data transmission.
Researchers have used this platform to demonstrate electrically-pumped
lasers emitting 40 billion pulses of light per second. because light can
move thousands of times faster through solid materials than electrons and
can carry more information at once, while requiring less energy.This is
the first ever achievement of such a rate in silicon. Creating optical
components in silicon will lead to optoelectronic devices that can
increase the amount and speed of data transmission in computer chips
while using existing silicon technology. optical chips based on silicon
photonic crystals would include their reduced risk of overheating due to
lower power needs.
