Abstract
AbstractFuture generation communication and computation system are dealing with ultra-high-speed data transfer, systematic management as well as lower cost. So the researchers are motivated to implement the different logic gates, digital devices, combinational circuits, optical computers. In optical computing systems, the parity generator is familiar as an essential part. In the case of all-optical devices design, reflective semiconductor optical amplifiers (RSOAs) appear as a promising candidate. Due to the versatile gain medium of RSOA, it has various important applications in passive optical networks. In comparison with semiconductor optical amplifiers (SOAs), RSOAs exhibit better gain performance because of their double pass property. Therefore, a frequency encoded dibit-based 4-bit parity generator is designed using low-cost RSOA. It shows also better switching properties. This design operates at a high speed. This device is benefited with dibit-based logic as reduces bit error problem. MATLAB Simulink (R2018a) software is used to verify the proposed design.KeywordsDibit-based logic systemReflective semiconductor optical amplifierAdd/drop multiplexerParity generatorFrequency encoding
