Elementary reflected code converter using a silicon nitride-based microring resonator

摘要

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.
