Dibit-based NAND gate using Reflective Semiconductor Optical Amplifier

In the all-optical domain, the reflective semiconductor optical amplifier (RSOA) creates due attention in the research community because the RSOA has high gain, low power consumption, high-speed signal processing ability as well as low noise performance. In this work, we have proposed dibit-based NAND gate using RSOA. Dibit-based logic is utilised in this design to get the reduced bit-error problems and high degree of parallelism. To verify the functionality of the aforementioned design, we have used MATLAB software and also the quality factor (Q), contrast ratio (CR), extinction ratio (ER), and bit-error-rate (BER) have been calculated.
