Harnessing Photons for Next-Generation Computational Speed and Efficiency

In today's technological age, computers have greatly improved people's daily lives. Though computer processing speeds are extremely fast when compared to human abilities, they still need to be significantly increased to meet future demands. This is in contrast to the relatively exponential growth in the advancement of other technologies that rely on computers. There is no longer any hope for electrons since humans have driven them to their absolute limit. Photons, on the other hand, may substitute for the slower electrons. Something that can do everything an electron can, but at a million times the speed and with significantly greater dependability in some manner, taking computing to a level nobody could have imagined. This study presents the applications of photonics in the computing industry, discusses their potential as an alternative to electrons, and compares the two from a computational standpoint. It also covers the generalized operation of optical computers based on silicon, the applications of photons, and their critical role in the future.
