Z-domain mathematical modeling and performance analysis of ripple ring resonator (RRR) with design of all-optical arithmetic logic unit (ALU)

摘要

A novel ripple ring resonator (RRR) structure is proposed and analyzed by coupling two and three optical microring resonators (OMRRs). All-optical arithmetic logic unit (ALU) with seven operations is presented using the proposed RRR structure. The mathematical pedestal is derived in Z domain using delay line signal processing. The simulation presented using MATLAB. The RRR performance is analyzed in terms of different quality metrics, giving promising results and has integration compatibility with complementary metal?oxide semiconductor (CMOS) photonic technology.
