Generation of optical combs in a whispering gallery mode resonator from a bichromatic pump

, 2009
An optical comb is shown to arise from a whispering gallery mode resonator pumped by two optical frequencies. Two externally excited modes couple due to Kerr nonlinearity to initially empty modes and give rise to new frequency components.

Ray and wave chaos in asymmetric resonant optical cavities

, 1998
Optical resonators are essential components of lasers and other wavelength-sensitive optical devices. A resonator is characterized by a set of modes, each with a resonant frequency omega and resonance width Delta omega=1/tau, where tau is the lifetime of

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Light and sound interplay in whispering gallery mode resonators

Journal of the European Optical Society-Rapid Publications
Whispering Gallery Mode Resonators (WGMRs) are robust and compact structures that confine resonant photons and phonons for extended time. This extraordinary confinement greatly enhances light and sound interactions and allows a plethora of fundamental ...
