Electro-Optomechanical Modulation Instability in a Semiconductor Resonator
Abstract
In semiconductor nano-optomechanical resonators, several forms of light-matter interaction can enrich the canonical radiation pressure coupling of light and mechanical motion, and give rise to new dynamical regimes. Here we observe an electro-optomechanical modulation instability in a Gallium Arsenide disk resonator. The regime is evidenced by the concomitant formation of regular and dense combs in the radio-frequency and optical spectrums of the resonator, associated with a permanent pulsatory dynamics of the mechanical motion and optical intensity. The mutual coupling between light, mechanical oscillations, carriers and heat, notably through photothermal interactions, stabilizes an extended mechanical comb in the ultra-high frequency range, which can be controlled optically.
