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…

This Publisher’s Note is for a typographical correction to the funding section of Optica6, 213 (2019)OPTIC82334-253610.1364/OPTICA.6.000213. The name of a funder was corrected.

Stimulated Brillouin scattering and Brillouin-coupled four-wave-mixing in a silica microbottle resonator.

We report the first observation of stimulated Brillouin scattering (SBS) with Brillouin lasing, and Brillouin-coupled four-wave-mixing (FWM) in an ultra-high-Q silica microbottle resonator. The…

Integrated optical circulator by stimulated Brillouin scattering induced non-reciprocal phase shift.

Though the bandwidth is relatively small because of the narrow-band nature of microresonator, this magnetic-free all-optical integrated circulator may be applied for future on-chip photonic information processing.
