Abstract
A fiber optic energy sensor and optical demodulation system is disclosed wherein the signal energy to be sensed or detected causes an etched single mode fiber to be stretched or compressed which causes the optical path length for electro-magnetic radiation traveling in the core of the optic fiber to change. The change in optic path length modulates the electro-magnetic radiation traveling in the fiber. There is also disclosed novel methods of manufacturing the novel type of fiber optic energy sensor and optical demodulation system.
