New all-optical gray code converter circuit using nonlinear switching techniques based micro-ring resonator

The field of modern ultra-speed secured Information processing in optical communication nonlinear photonics is one of the options. The Switching action through a Micro-ring Resonator can be used to implement an all-optical gray code converter circuit with some added advantages e.g. microstructure, secure data processing, and ultra-bandwidth. The paper explained the switching action of the MRR structure along with the implementation of well-organized optical 4-bit code converter circuits. The layouts and switching techniques of all-optical desired 4-bit gray code converter circuits have been thoroughly described, and corresponding simulation results using MATLAB have been shown to verify the proposed unit's appropriateness. These techniques reduce the size of the optical circuit and make it more compact to incorporate with Very Large Scale Integrated Optics (VLSIO). The proposed unit avoids the complex issues related to electro-optic and optoelectronics signal conversion. A 4-bit gray code converter in the optical domain comprises certain significant gains of secured optical signal communication. Finally, the manuscript defines a competent performance to implement an all-optical MRR based desired gray code converter circuit.
