Abstract

Herein, a cross-grid microring resonator electro-optic switching array model is proposed on the basis of the coupled mode theory, electro-optic modulation theory, and microring resonance theory. The proposed device has N+1 horizontal channels, N vertical channels, and 2N microrings with equal radii. By applying an operating voltage to the microrings in the array unit in various ways, the switching function of the N+1 horizontal channel can be realized. Taking the structure of 9 × 8 channels as an example, the output spectrum, insertion loss, crosstalk, extinction ratio, and other characteristics of this switching array device under a resonant wavelength of 1550 nm are simulated and analyzed.
