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. An electric current flows at only about 10 percent of the speed of light. This restricts the rate at which information can be exchanged over long separations, and is one of the components that prompted the advancement of optical fiber. By applying a some of the benefits of unmistakable and additionally IR systems at the gadget and part scale, a PC may some time or another be built up that can perform tasks 10 or more times faster than a conventional electronic computer.
In Principle, speaking with light is much simpler than speaking with power. We’ve been doing it for longer, in innovations running from signal fires to fiber-optic systems, since photons have the ability to move information for more faster than electrons. However, light likewise has many frustrating issues that electrons don’t — issues that have shielded light from dislodging power on the nanometer sizes of present-day computing. For a long, the real impediment to a photonic transformation in computing, and an exponential increment in computer speed has been a kind of lose situation between three major players: size, power, and heat. Also, the following reasons are of need,
