What is optical Computing
It is the science of making computing faster
using optical signals instead of electrons
Optical Transistors & Logic Gates
Basic Speed Parameter for Optical Devices is
Switching Time
Switching Process Takes Place Using Light Pulses
Work on the principle of the Bending or Refraction of Light
in a Photonic Crystal.
Evident Technologies USA Devised an Optical Transistor
with a switching time of 1 Picoseconds.
Stanford and MIT researchers Designed Optical Switch
and an Optical Transistor with Size Less than 1 micron
All-Optical devices on chips can be feasible as early as 2005-
2008
Features of Optical Processor
1,000 times faster than standard processors
Chip uses the Parallel-Processing Power of Light
with 256 lasers performing computations at light speed
Conclusion
Electro-Optic Hybrid Deices Have Been Devised but Entirely Optical Computers Are Still Some Time in Future
Because
There is no Consortium that Has Defined Any Kinds of Standard for Optical Computing So The Research is Scattered and Opticalisation is Happening Component by Component.
There is a Tremendous Need for New Materials That Can Be Deemed as Being Capable of Implementing What is Being Done in Theory
We don’t Yet Have a Clear Idea What a Fully-Optical Computer Will Be Like.
