Abstract: Optical decoders are essentially required components for creating all-optical digital systems used in optical data processing and logical operations. In this paper, a novel structure of a 2*4 optical decoder is proposed for design using a two-dimensional photonic crystal (2D PhC). The proposed decoder is based on silicon rod photonic crystals with four output ports, two input ports, and a biasing port. For logic, 0 and 1 are introduced based on the maximum, and minimum power levels (0.1Pin and 0.37Pin), where Pin is the input power. Analyze of 2*4 decoder presented here is done using the Finite Difference Time Domain and Plane Wave Expansion methods—which provide the result of all functional parameter simulation and band structure of the lattice, respectively. The results show that the proposed 2*4 optical decoder with optimized functional parameters is suitable for all-optical information processing in future. [ABSTRACT FROM AUTHOR]

Abstract:Optical decoders are essentially required components for creating all-optical digital systems used in optical data processing and logical operations. In this paper, a novel structure of a 2*4 optical decoder is proposed for design using a two-dimensional photonic crystal (2D PhC). The proposed decoder is based on silicon rod photonic crystals with four output ports, two input ports, and a biasing port. For logic, 0 and 1 are introduced based on the maximum, and minimum power levels (0.1P<subscript>in</subscript> and 0.37P<subscript>in)</subscript>, where P<subscript>in</subscript> is the input power. Analyze of 2*4 decoder presented here is done using the Finite Difference Time Domain and Plane Wave Expansion methods—which provide the result of all functional parameter simulation and band structure of the lattice, respectively. The results show that the proposed 2*4 optical decoder with optimized functional parameters is suitable for all-optical information processing in future. [ABSTRACT FROM AUTHOR]
