Electro-Optomechanical Modulation Instability in a Semiconductor Resonator, Phys. Rev. Lett. 126, 243901 (2021).
Evolution of a GaAs disk optomechanical resonator from self-oscillation to a mechanical comb formation. The electro-optomechanical modulation instability radio-frequency spectrum is shown as a function of the driving laser wavelength: experiment (upper); theory (lower).
