ABSTRACT:
Fiber sensors formed on side-polished fiber coupling ports based on evanescent coupling are described. Such sensors may be configured to measure various materials and may be used to form multi-phase sensing devices. A Bragg grating may be implemented in such sensors to form reflective fiber sensors.
