Thermal isolation structure

Abstract:

Disclosed here is a system including a multi-wavelength integrated light source having one or more heaters. The system can comprise a substrate including a light source section, the heater(s), and a plurality of sections. The sections can include multiple materials, where the material for a given section can be based on one or more targeted criteria. For example, one section can have a targeted criteria of being optically transparent. Another section can have a targeted criteria of providing mechanical support, and another section can have a targeted criteria of being a thermal insulator. In some instances, openings in the substrate can be formed and filled with one or more materials to form a window (e.g., a section having a targeted criteria of being optically transparent) and a thermal isolator (e.g., a section having a targeted criteria of being thermally insulating).
