Simulative analysis of all-optical reflective semiconductor optical amplifier based 2-to-4 line decoder and read only memory (ROM)

Abstract

Abstract In this paper, all-optical 2-to-4 line decoder and read-only memory (ROM) are analyzed using a Reflective Semiconductor Optical Amplifier (RSOA) based optical switch. The structures of these 2-to-4 line decoder and read only memory are very simple and the operating speed is 200 Gbps, which can be used in optical hardware systems. The 2-to-4 line decoder output shows a very high extension ratio (ER), contrast ratio (CR), and Q value. These high values indicate the distinguishment between two states (‘1’ and ‘0’) very clearly.
