Abstract

Whispering gallery mode (WGM) resonators with high quality-factors (Q) have been used for high-sensitivity refractometric sensing. The sensitivity can be further enhanced by using Fano resonances[1]. Apart from this, Fano resonances are also useful for sub-diffraction focusing in super-resolution microscopy [2]. Here we report the observation of Fano resonances in self-assembled microbottle resonators (MBRs). MBRs are WGM microcavities with highly prolate-spheroidal shape. MBRs show modes that extend along the z-axis of the resonator, known as higher order axial modes or bottle modes. Self-assembly is a simple and robust method to fabricate MBRs. We have self-assembled MBRs made of polymethyl methacrylate (PMMA), a high quality optical polymer, on a tapered optical fibre. The mode spectrum of these self-assembled MBRs show Fano resonances. ...& more.
