ABSTRACT:
A thermo-optic device may be formed with trenches that undercut the substrate beneath the thermo-optic device. Through the removal of the underlying substrate, the heat dissipation of the thermo-optic device may be reduced. This may reduce the thermal budget of the device, reducing the power requirements for operating the device in some embodiments.
