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 bulk material of the resonators, usually cause some amount of Rayleigh scattering between the modes [1]. For sufficiently high levels of backscattering, the coupling between the modes can be observed as a resolvable splitting in the frequency domain [2]. Coupling of the modes is unfavourable for some WGM resonator applications, for example gyroscopes [3] , dual frequency combs [4] , and applications relying on symmetry breaking of counter-propagating light [5] , [6].
