Abstract

Various aspects of this disclosure provide a bolometer including a substrate and a ring resonator structure over the substrate. The bolometer may also include a silicon oxide layer in thermal contact with the ring resonator structure. The bolometer may further include a first waveguide over the substrate and coupled to the ring resonator structure, the first waveguide configured to couple an infrared light to the ring resonator structure so that the infrared light generates a temperature increase in the silicon oxide layer. The bolometer may additionally include a second waveguide over the substrate and coupled to the ring resonator structure, the second waveguide configured to couple a probe light input to the ring resonator structure so that a probe light output is generated from the probe light input, the probe light output having a change in a characteristic from the probe light input based on the temperature increase.
