Acousto-optic Modulation of the Cavity Resonant BIC Modes

Caption

(a, b) Measured S21 spectra for devices with SAW interdigital transducer finger period Λ = 2w (a) and Λ = 2w/3 (b). (c) Illustration of the three-wave mixing process of the control light (ωc), probe light (ωp), and SAW (ΩSAW). The cavity resonant frequency is ω0 with a decay rate of κ. (d) Measured normalized transmission spectra of the probe light, showing the features of electro-acousto-optically induced transparency and absorption
