Optical Computers

1.0 Introduction Com prepareers have enhanced human life to a owing(p) extent.The goal of improving on computer velocity has resulted in the development of the Very Large Scale Integration (VLSI) engine room with smaller device dimensions and greater complexity. ¬¬¬ VLSI engine room has revolutionized the electronics industry and additionally, our hourly lives demand solutions to increasingly sophisticated and complex problems, which requires more(prenominal)(prenominal) speed and break out surgical operation of computers. For these reasons, it is unfortunate that VLSI technology is approaching its profound limits in the sub-micron miniaturization process. It is now possible to fit up to ccc million junction transistors on a single ti chip. As per the Moore¬s law it is also estimated that the number of transistor switches that can be put onto a chip restate every 18 months. Further miniaturization of lithography introduces several problems such(prenominal ) as dielectric breakdown, hot carriers, and short channel effects. every(prenominal) of these factors unify to seriously degrade device reliability. Even if development technology succeeded in temporarily overcoming these physical problems, we exit stay put to face them as long as increasing demands for amply integration continues. Therefore, a dramatic solution to the problem is needed, and unless we huckster our thoughts toward a totally different path authority, we will non be able to further improve our computer comeance for the future. optic interconnections and optical integrated circuits will provide a way out of these limitations to computational speed and complexity intrinsic in conventional electronics. Optical computers will use photons traveling on optical fibers or thin films instead of electrons to perform the get functions. In the optical computer of the future, electronic circuits and wires will be replaced by a few optical fibers and films, devis ing the systems more efficient with no inter! ference, more cost effective, flatboat and more compact.
