Abstract:
1. A thermo-optic device, comprising: a first cladding with a surface and at least one depression in the surface; features on the first cladding, the features including a first waveguide extending from the first cladding to a top waveguide surface, a second waveguide and a resonator extending up from the first cladding to the top waveguide surface, the resonator disposed between the first waveguide and the second waveguide, at least one of the features positioned in the at least one depression of the first cladding to provide a desired waveguide/resonator aspect ratio for a desired bandwidth; a second cladding over and around the first waveguide, the second waveguide and the at least one resonator, wherein the resonator is a first resonator in a first depression; and a second resonator in a second depression in the first cladding.
