Analysis of a Silicon Dual-Coupled-Ring Resonator Modulator Based on Push–Pull Coupling Tunings


We present a silicon dual-coupled-ring resonator modulator with push–pull coupling tunings. The basic idea of this scheme is to construct a dual-coupled-ring resonator structure in which the coupling coefficients of all coupling regions are tunable through Mach–Zehnder interferometers operated in push–pull modes. Two coupling coefficients are tuned jointly… (More)
