Abstract

In a birefringent optical microcoil resonator novel effects occur that cannot be seen in normal optical microcoil resonators. In this paper we discuss some of them such as Berry phase magnification as well as polarisation switching in the nonlinear regime. Optical microcoil resonators (OMRs) fabricated by wrapping a microfibre around a rod to allow evanescent coupling between adjacent turns as in Fig 1. (a) have recently attracted much interest due to their high Q-factor and large extinction ratios resonances, low input and output coupling losses, large evanescent field and compactness [1,2], with applications such as sensing [3] and signal processing [4]. However, theoretical models published so far have neglected polarisation effects, and hence in order to develop a more detailed understanding we have modelled the OMR with polarisation-dependent coupled mode equations in the linear [5] and nonlinear regimes. We first examine the effects of including a Berry phase term then look at nonlinear effects in birefringent OMRs.
