Optics: suppressing backscattering improves performance of microresonators A technique that suppresses backscattering in optical whispering-gallery-mode (WGM) microresonators significantly improves their performance, opening the door for their use in

Optical logic has the potential to replace electronics with photonic circuits in applications for which optic-to-electronic conversion is impractical and for integrated all-optical circuits. Nonlinear optics in whispering gallery mode resonators prov

Optical gyroscopes based on the Sagnac effect have been the mainstay of inertial navigation in aerospace and shipping for decades. These gyroscopes are typically realized either as ring-laser gyroscopes (RLGs) or fiber-optic gyroscopes (FOGs). With t

Optical modes in whispering-gallery-mode (WGM) resonators generally come in pairs of degenerate modes with opposite propagation directions: a clockwise and a counter-clockwise mode. However, sub-wavelength-size imperfections on the surface and in the

As light propagates along a waveguide, a fraction of the field can be reflected by Rayleigh scatterers. In high-quality-factor whispering-gallery-mode microresonators, this intrinsic backscattering is primarily caused by either surface or bulk materi

The Kerr effect in optical microresonators plays an important role for integrated photonic devices and enables third harmonic generation, four-wave mixing, and the generation of microresonator-based frequency combs. Here we experimentally demonstrate

We show > 30 dB suppression of intrinsic backscattering in ultra-high-quality factor whispering gallery mode resonators by controlling the position of a sub-wavelength scatterer within the evanescent field of the resonator.

We observe two-fold and three-fold splitting of optical modes in ultra-high-Q microresonators induced by the Kerr effect. This can be used for applications that require multiple resonances with precisely controlled offset.

We use kerr-interaction between counter-propagating light waves in a whispering gallery mode resonator to demonstrate a universal, all-optical, logic gate. This provides a novel path for on-chip routing of light.

Recent work [1–4] has demonstrated spontaneous breaking of clockwise-counterclockwise symmetry in a bidirectionally-pumped passive optical microresonator, mediated by the Kerr effect. The critical point of this symmetry breaking exhibits universal
