  • Publication number: 20230134264
    Abstract: An optical sensing apparatus is provided comprising: an input interface for receiving input light into the optical sensing apparatus; an input waveguide and a reference waveguide, both arranged to receive input light from the input interface; a closed loop resonator, wherein the input waveguide is optically coupled to the closed loop resonator at an input point for introducing input light to the closed loop resonator; a sample region, adjacent the closed loop resonator, for receiving a sample such that evanescent coupling can occur between light in the closed loop resonator and the sample; a drop-port waveguide, optically coupled to the closed loop resonator at a drop point for receiving dropped light from the closed loop resonator; an output waveguide; and an output interface. The reference waveguide and the drop-port waveguide are arranged to direct interfering light through the output waveguide to produce an output signal at the output interface.
