ABSTRACT:
An apparatus and method for use with a coherent optical source to detect environmental changes. The apparatus comprises: an optical cavity, including an input coupling port, and an optical fiber section; a detector optically coupled to the optical cavity to monitor radiation in the optical cavity; and a processor electrically coupled to the detector for analyzing the environmental changes adjacent the detection portion of the optical cavity based on a rate of decay of the radiation in the optical cavity monitored by the detector. The optical fiber section of the optical cavity includes a detection portion coated with a conductive layer capable of supporting a surface plasmon to provide cavity loss. The surface plasmon is responsive to the environmental changes adjacent the detection portion. The coherent optical source is optically coupled to the input coupling port of the optical cavity to provide the radiation in the optical cavity.
