NEW ERA OF OPTICAL COMPUTATION

In today’s world, it will not be wrong to say that “DATA IS THE NEW OIL.” One who has the information holds the key to everything. Countries today play their diplomatic games based on the information they possess. Business runs on the prediction of the future demands which are obtained by analyzing the huge database created by the users. The introduction of Android phones, smart devices, and AI assistants are basically mining user’s information, and that information is free of cost. The new strategy is to give unlimited and free internet to the user so that his system is connected to the web for a longer duration of time and he creates more information. This information is analyzed and used for a variety of purposes. People are hired by various companies to analyze such type of data to get their shopping pattern, spending pattern and consumer’s preferences.

The entire system of generation, transportation, and processing of this humongous magnitude of information (data) rests heavily on the network which carries them. To keep this system working effectively, there should be no lags in the data carrying the network. The optical fiber network is used for the transportation of data. As we all know that the major advantages of optical fiber are high speed (it transports data at the speed of light) and high bandwidth which are the very requirements for the efficient communication system. When the data arrives at the receiving end of the network, they have to go through the electronic processors, which are actually lowering the capacity of the communication system. The incoming data which is optical in nature has to be converted into its electronic form for further processing. This puts limitations on the high speed and bandwidth provided by the optical networks. Now the electronic processors cannot process at the optical speed and bandwidth. Even if they are clocked to do, so there is an enormous amount of heat dissipation from the circuits. Since the data is huge and high speed; therefore, heat dissipation is also high, which harms the hardware once it crosses a certain threshold. To overcome this problem researchers are looking towards all-optical processing of the incoming optical signals. The idea is to develop all-optical processors which will eliminate optoelectronic conversions. This will not only increase the efficiency of the entire communication system but will also prevent the hardware damages which proves very costly. Slowly but steadily the designing of the optical circuits are being implemented. Links of the research papers on designing of optical gates are given below:
