A Nonlinear Enhanced Microresonator Gyroscope

Optics 2020-01-16 v1

Abstract

We demonstrate a novel optical microresonator gyroscope whose responsivity to rotation is enhanced by a factor of around 10410^4 by operating close to the critical point of a spontaneous symmetry breaking transition between counterpropagating light. We present a proof-of-principle rotation measurement using a resonator with a diameter of 3 mm. In addition, we characterise the dynamical response of the system to a sinusoidally varying rotation, and show this to be well described by a simple theoretical model. We observe the universal critical behaviors of responsivity enhancement and critical slowing down, both of which are beneficial in an optical gyroscope.
