This article presents a simple and unique design for the generation of an all-optical reflected code or Gray code converter using an optical microring resonator as a basic building block. The Si3N4 -based microring resonator is modulated using an optical pump signal. The paper includes a combination of microring resonators for the generation of a reflected code encoder logic circuit. The designs are studied mathematically and results are proved using simulations. Various parameters including quality factor, on–off ratio, extinction ratio, finesse and free spectral range (FSR) are also determined for the designed structure, which confirms the practicability of the proposed circuit.
