Abstract
In one embodiment, a photonic integrated circuit (PIC) device includes conductive pads on a surface of the PIC and a micro ring resonator (MRR) with a heater element centrally located between the conductive pads. The PIC also includes a cavity defined within a substrate of the PIC below the MRR, and a plurality of holes defined between the MRR and the conductive pads. The holes extend from a top surface of the PIC into the cavity, and each hole is between a respective conductive pad and the MRR.
