A novel approach of developing all-optical frequency encoded dibit-based Peres gate using reflective semiconductor optical amplifier

Abstract

In recent trends, digital systems in the light of power dissipation are a crucial issue. In computing, the computational process of reversible logic is bijective and can decrease the rising issue of power dissipation. In reversible circuit design, Peres gate considered as one of the fundamental reversible gate. Therefore, a Peres gate using Add/Drop Multiplexer (ADM) and Reflective Semiconductor Optical Amplifier (RSOA) is proposed in this paper. Frequency encoding scheme and dibit-based logic are incorporated here. In long range transmission, frequency encoding bears huge benefits in respect with the other encoding techniques. This encoding technique may decrease the probability of bit error. Due to the high gain and low noise property of RSOA, the proposed design can perform operations like computation, data processing, etc. at ultra-high speed with low noise. MATLAB Simulink (R2018a) software has been used to verify the operation of the proposed design.

Alternative approach to design Dibit-based XOR and XNOR gate

“…Here, presence of soliton pulse takes as digital state '1' and absence of the pulse takes as '0'. The dibit-based [23] logic means when two bits are taken back-to-back, i.e., '01' and '10'. Here, dibit logic '01' and '10' are specify the digital logic state '0' and '1' respectively.…”
