Abstract

We study the oscillatory thermal dynamics of a high-Q PDMS-coated silica microtoroid both experimentally and theoretically. We demonstrate that the competing thermo-optic effects in silica and PDMS lead to thermally-induced self-modulation in the transmission spectra. A dynamical model is built using thermal dynamics and coupled-mode theory to analyze the oscillation behaviors. Effects of input power, taper-cavity air gap and wavelength scanning speed on the oscillation behaviors are investigated with a detailed comparison between theory and experiments.

  27. The reason for the fast temperature variations within the mode volume in PDMS is twofold. First, the volume of PDMS layer is much smaller than that of the bulk silica core, therefore thermal dissipation from the mode volume to PDMS layer is faster than to silica. Second, most optical losses are concentrated in PDMS layer due to its larger absorption coefficient than silica, so that PDMS absorbs more energy.
