Controllable multichannel acousto-optic modulator and frequency synthesizer enabled by nonlinear MEMS resonator

Abstract Nonlinear physics-based harmonic generators and modulators are critical signal processing technologies for optical and electrical communication. However, most optical modulators lack multi-channel functionality while frequency synthesizers have deficient control of output tones, and they ad...
