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

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.

Analysis of 2D Photonic crystal based all optical comparator

“…To build an optical device, different components such as optical gate, optical switch, memory etc are the requirement. In recent years, all optical logic gates and processors are designed using different switching mechanism such as, SOA, RSOA, TOAD, DCDSTOAD, ring resonator etc., with higher speed, smaller size and lower heat dissipation [2][3][4][5][6][7][8][9][10][11][12][13][14]. However, these devices have several disadvantages in terms of lower speed of operation, effect of spontaneous emission noise, higher foot print etc.…”
