Design and Performance Analysis of All Optical Half Adder based on Carrier Reservoir SOA -Mach Zehnder Interferometer (MZI) Configuration

In this manuscript, Carrier reservoir SOA (CR-SOA) based half adder is proposed and simulated at 100 Gb/s. CR-SOA has fast carrier recovery, due to presence carrier reservoir which enables its use at higher data rates on the other hand conventional SOA suffers from slow carrier recovery which leads to unequal amplification of pulses. The obtained results confirm that proposed design can be realized effectively at target data rate with acceptable Q factor.
