Abstract
An agent sensing system may comprise an emitter optical resonator, a functionalized optical resonator, and a reference optical resonator. The emitter optical resonator may be configured to emit light at one or more system peak wavelengths. The functionalized optical resonator may be optically coupled to the emitter optical resonator and configured to propagate the emitted light in the absence of a particular agent, and filter the emitted light in the presence of the particular agent. The reference optical resonator may be optically coupled to at least one of the emitter optical resonator and the functionalized optical resonator such that an intensity of light propagated by the reference optical resonator is based at least on whether light emitted by the emitter optical resonator is filtered or propagated by the functionalized optical resonator.
