Abstract

A phase shifter includes a substrate layer, a cladding layer, and a waveguide. The phase shifter includes a waveguide and a heating element. The phase shifter includes a thermally conductive structure disposed on the cladding layer to disperse heat from the waveguide. The thermally conductive structure may include a metal strip disposed longitudinally along the beam, may include thermally conductive pads, and/or may include thermally conductive vias coupled between the cladding layer and the substrate layer. The phase shifter may be incorporated into light detection and ranging (LIDAR) devices, telecommunications devices, and/or computing devices.
