Realization of an all-optical d and t flip flops with nano-structure using hybrid plasmonic waveguides

Abstract

1310 nm operating wavelength, and a transmission threshold (T threshold ) of 30% is shown using hybrid plasmonic waveguides (HPWGs) for Electro-Opto applications. It offers the basic structure for creating optical computers. The results of this structure are evaluated in a term of Contrast Ratio (CR), Modulation Depth (MD), and Insertion Losses (IL). The D-flip flop had an Insertion Loss of -1.4 dB, a CR of 7.45 dB, and a MD of 97.67%. The T-flip flop had an IL of -2.07 dB, a CR of 11.2 dB, and a MD of 95.29%. The mechanism that governs the operation of the suggested circuits depends on the constructive and destructive interferences between input ports and control ports. The simulation is based on the finite element method utilizing COMSOL software package version 5.5.
