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

When on-chip microresonators were first fabricated in 2005, it became apparent that these cavities exhibit op-tomechanical properties, evident by the parametric oscillation instability that was observed [1] , [2] . This behaviour, resulting from radi

Photonics in Switching and Computing 2021.
We achieve an all-optical, universal logic gate based on the Kerr-effect in whispering gallery mode resonators. Switching is achieved via direction-dependent and nonreciprocal Kerr interaction between counter-propagating light.

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 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.

Frontiers in Optics / Laser Science.
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

The Kerr effect in microresonators is usually masked by thermal effects [1], as resonances can thermally drift on the order of a few GHz, compared to Kerr effect shifts of a few MHz. However, the Kerr effect, and in particular cross-phase modulation
