Ultrafast carrier reservoir semiconductor optical amplifiers-based all-optical and logic gate

It has become an imperative reality to find an alternative for the conventional bulk semiconductor optical amplifier (SOA), which suffers from the slow dynamic response, in light of the increased need for higher speeds. In this research, the carrier reservoir SOA (CR-SOA) is employed as a suitable alternative to investigate the all-optical AND logic gate for the first time at an operating speed of 100 Gb/s. For the reliability of the results, the CR-SOAs- A nd the conventional SOAs-based Mach-Zehnder interferometer are compared in the same operating conditions that include the effects of the amplified spontaneous emission noise and the operating temperature to obtain more realistic simulation results. The results of Wolfram Mathematica proved that the considered Boolean function is executed at 100 Gb/s with a higher quality factor when using CR-SOAs compared to SOAs, i.e., 14 versus 4.7.
