Acousto-optic devices utilize the overlap of acoustic and optical fields to facilitate photon-phonon interactions. For tightly confined optical and acoustic fields, such as the sub-wavelength scales achievable in integrated devices, this interaction is enhanced. Broadband operation which fully benefits from this enhancement requires light and sound to co-propagate in the same cross-section, a geometry currently lacking in the field. We introduce the `acoustic-optical multiplexer', which enables…

Energy-efficient active integrated photonic isolators using electrically driven acoustic waves

We propose and investigate the performance of integrated photonic isolators based on a triply-guided waveguide system on chip comprising two optical modes and an electrically-driven acoustic mode.

Coherent coupling between radio frequency, optical, and acoustic waves in piezo-optomechanical circuits.

An acoustic wave interference effect, similar to atomic coherent population trapping, is demonstrated, in which RF-driven coherent mechanical motion is cancelled by optically-driven motion.

Non-reciprocal interband Brillouin modulation

Non-reciprocal light propagation is essential to control optical crosstalk and back-scatter in photonic systems. However, realizing high-fidelity non-reciprocity in low-loss integrated photonic
