Abstract

A thin-walled microbubble whispering gallery resonator was fabricated and filled with a polymer (Polydimethylsiloxane : PDMS) to form a polymer quasi-droplet optical microcavity. The thermal shifting of the whispering gallery modes (WGMs) was studied pre and post curing of the polymer. In both cases, large thermal shifts were observed. However, the sign of the shift changed as the polymer hardened. The final state of the cavity showed a large red shift of the modes. Complex mode mixing was also observed which results in EIT (electromagnetically induced transparency) and Fano-like resonances. The time response of the polymer-filled bubble was investigated demonstrating regenerative self-oscillation for a fixed laser detuning with a low threshold power.
