Abstract
A device for providing a controlled back-reflection of a preselected port of incident fiber-guided light while minimizing the affect to light continuing down the fiber. The back-reflected light couples to the reverse traveling fiber mode with minimal loss. These devices are used as reflectors in a pulse sampled fiber optic hydrophone array.
