Abstract
A thermally tunable microresonator device with enhanced thermal confinement for greater efficiency is provided. A thermal confinement structure is electrically connected in series with the heater element used for tuning the microresonator. The heater element is conformed in a circular arc concentric with the microresonator, the thermal confinement structure comprises two or more tiers, and each tier comprises at least one metal trace conformed in a circular arc concentric with the microresonator.
