A design of all-optical read-only memory using reflective semiconductor optical amplifier

In recent times, any device should be designed with taken care of power consumption as well as speed. Photon has super-fast speed so it is very preferable to the researcher rather than the electron. So the researchers focus on the development of low-power-consuming devices. The reflective semiconductor optical amplifier (RSOA) is a suitable candidate for that purpose. It has a versatile gain medium and also it has huge application in passive optical networks. In this article, we have proposed a design of read-only memory using RSOA. To verify the practical feasibility, we have used MATLAB software to simulate the design. For all the memory outputs, the quality factor (Q), extinction ratio, contrast ratio, and also bit error rate have been calculated.
