Tutor description

An optical computer (also called a photonic computer) is a device that uses the photons in visible light or infrared (IR) beams, rather than electric current, to perform digital computations. Optical computing could produce computers tens of thousands of times faster than today's computers Optical computers will use photons traveling on optical fibers or thin films instead of electrons to perform the appropriate functions. Electronic circuits and wires will be replaced by a few optical fibers and films, making the systems more efficient with no interference, more cost effective, lighter and more compact

Optical Computers In most modern computers, electrons travel between transistor switches on metal wires or traces to gather, process and store information. The optical computers of the future will instead use photons traveling on optical fibers or thin films to perform these functions. But entirely optical computer systems are still far into the future. Right now scientists are focusing on developing hybrids by combining electronics with photonics. Electro-optic hybrids were first made possible around 1978, when researchers realised that photons could respond to electrons through certain media such as lithium niobate (LiNbO3). To make the thin polymer films for electro-optic applications, NASA scientists dissolve a monomer (the building block of a polymer) in an organic solvent. This solution is then put into a growth cell with a quartz window. An ultraviolet lamp shining through thi
