We report the electrical control of coherent Brillouin interaction based induced transparency resonances in the microwave domain using single mode fiber. We show an extinction of about 30 dB from 10

Inter-modal Brillouin scattering in an integrated waveguide

We report strong stimulated Brillouin scattering between light guided in separate spatial modes of an integrated waveguide for the first time. Through this process, we demonstrate 2.3 dB of

Non-Reciprocal Delay Based on Photon-Phonon Interactions on a Chip

We demonstrate a non-reciprocal delay scheme based on stimulated Brillouin scattering in a planar highly nonlinear waveguide. The bandwidth of this scheme approaches a GHz, has wide frequency

Suppression of Rayleigh Backscattering in Resonators

We demonstrate dynamic suppression of Rayleigh backscattering in a whispering gallery mode resonator by locally breaking time-reversal symmetry through a Brillouin optomechanical interaction.

Nanoscale Isolation with Circularly Polarized Stimulated Raman Scattering in a Doubly-resonant Silicon Metasurface for Subwavelength Nonreciprocity

Nonreciprocal devices allow light to pass in one-direction only, which is critical for the stable operation of photonic systems, but conventional isolators remain prohibitively large. We fabricate

Non-magnetic non-reciprocal transparency and amplification is experimentally achieved by optomechanics using a whispering-gallery microresonator. The idea may lead to integrated all-optical isolators

Implementing non-reciprocal elements with a bandwidth comparable to optical frequencies is a challenge in integrated photonics. Now, a phonon pump has been used to achieve optical non-reciprocity

An experimental demonstration of Brillouin-scattering-induced transparency in a high-quality whispering-gallery-mode optical microresonantor establishes a new avenue towards integrated all-optical switching with low-power consumption, optical isolators and circulators.

Observation of spontaneous Brillouin cooling

A novel mechanism for cooling tiny mechanical resonators is now demonstrated. Inelastic scattering of light from phonons in an electrostrictive material attenuates the Brownian motion of the
