ALL-OPTICAL FREQUENCY ENCODED DIBIT-BASED PARITY GENERATOR USING REFLECTIVE SEMICONDUCTOR OPTICAL AMPLIFIER WITH SIMULATIVE VERIFICATION

High-speed signal computation and communication are an essential part of modern communication that increases optical necessity. Therefore, researchers developed different types of digital devices in the all-optical domain. Due to the versatile gain medium of reflective semiconductor optical amplifiers (RSOAs), it has various important applications in passive optical networks. In comparison with semiconductor optical amplifier (SOA), RSOAs exhibit better gain performance because of their double pass property. Therefore, RSOA shows better switching properties. In this communication, co-propagation scheme of RSOA is used to design and analyze a frequency encoded dibit-based parity generator. Taking the advantages of RSOA like high switching speed, low noise, high gain, and low power consumption, the proposed design achieves these qualities. This design simulated in MATLAB and simulated outputs accurately verify the truth table.
