A Design of Frequency Encoded Dibit-based Comparator Using Reflective Semiconductor Optical Amplifier with Simulative Verification

In this modern era, optical computing increases the chance of ultra-high-speed information processing. All-optical comparator is one of the necessary components of the optical computing systems. Here we have designed a low power frequency encoded comparator using reflective semiconductor optical amplifier. This proposed comparator can compare a single bit signal. This work is based on dibit concept which improves the bit error problems. The proposed comparator is realized by simulation in MATLAB Simulink (R2018a) software. The devised design with the integrating ability is very purposeful in optical communication and computation.
