How Does It Work?
Photonic circuits or photonic switches.
Organic compounds.
Optical computers that encode data using images and compute by transforming such images.
Photonic switching:-
An optical transistor with a non-linear refractive index is used.
The strong electric field of high intensity light (such as output of a laser) may cause a medium's refractive index to vary as the light passes through it, giving rise to nonlinear optics.
Advances in photonic switches:-
Optical logic gate is a switch that controls one light beam by another.
ON when the device transmits light.
OFF when it blocks the light.
Optical NAND and AND gates are now available.
Current limitation:-
Photonic circuit accuracy
(due to environmental effects on organic material been used)
Requirement of power
(not purely optic ,requires electrons for startup procedure mean to form laser beams.)
