1. An optical sensing system comprising:
- a first bus waveguide, the first bus waveguide comprising an input port that is in optical communication with a light source;
a second bus waveguide comprising a drop two port;
a microresonator optically coupled to the first and second bus waveguides;
an optical scattering center configured for alteration of a strength of optical coupling between the optical scattering center and the microresonator; and
a detector in optical communication with the drop two port, wherein the optical sensing system is configured so that, in the absence of a scattering center optically coupled to the microresonator, light launched at the input port couples to a first guided optical mode of the microresonator and the first guided optical mode primarily does not couple to the drop two port.
