1. A whispering gallery mode resonator module comprising:
- (a) an input coupler configured to receive input radiation having a frequency of between about 30 GHz and 3 THz;
(b) a dielectric waveguide having an input end coupled to the input coupler for receiving the input radiation, and an output end opposite the input end, the dielectric waveguide being sized and shaped to propagate the input radiation from the input end to the output end;
(c) a dielectric resonator positioned between the input end and the output end of the dielectric waveguide and offset from the dielectric waveguide, the dielectric resonator sized, shaped and positioned so as to cooperate with the dielectric waveguide to support at least one whispering gallery mode for the input radiation; and
(d) an output coupler coupled to the output end of the dielectric waveguide for outputting a transmission response having a resonance characteristic related to the at least one whispering gallery mode.

Abstract
A sensor system includes a source of input radiation having a frequency range between about 30 GHz and 3 THz, a whispering gallery mode resonator module coupled to the source for receiving the input radiation, and a detector coupled to the whispering gallery mode resonator module. The whispering gallery mode resonator module is configured to support at least one whispering gallery mode for the input radiation, and output a transmission response having a resonance characteristic related to the at least one whispering gallery mode. The detector detects the transmission response.
