Abstract:
A tunable optical device comprising an optical ring cavity and one or more pairs of electrodes for capacitive actuation of the optical tuning. Applying a potential difference to the electrodes applies a capacitive force to the optical ring cavity which changes the optical resonance frequency. The device can be used as a binary optical switch.

Claim (Index 20):
In a yet further form the invention may reside in a fabrication technique to reflow an optical ring cavity structure with electrodes comprising:\n under-etching the optical ring cavity in two stages; stopping the first under-etching stage before the material underneath the electrodes is etched away; applying heating with a CO 2  laser to melt the material of the optical ring cavity after the first under-etching stage, with the thermal conductivity of the material underneath the electrodes preventing electrode heating and damage; under-etching the optical ring cavity in a second stage to free the outer part of the cavity from the material underneath it and allow it to expand upon application of a capacitive force.
