Abstract
In some implementations, a photonic structure may include a substrate, an optical waveguide, a heating component attached to a region of the optical waveguide, and a thermal insulation material positioned between the substrate and the region of the optical waveguide. Additionally, the heating component may be configured to apply heat to the region of the optical waveguide, and the thermal insulation material may be configured to thermally insulate the substrate from the heat applied to the region of the optical waveguide.
