Abstract

An infrared detector includes a substrate in which a void is formed, a micro-resonator suspended over the void, an infrared absorber on an upper surface of the micro-resonator, a thermal isolation bridge supporting the micro-resonator, a first waveguide optically coupled with the micro-resonator, a second waveguide intersecting the first waveguide and optically coupled with the micro-resonator, a light source optically coupled with the first waveguide, and a photodetector optically coupled with the second waveguide.
