Abstract:
Optical devices having at least one whispering gallery mode cavity formed on a side-polished coupling port of a fiber or waveguide based on evanescent coupling are described.
Abstract:
Fiber sensors formed on side-polished fiber coupling ports based on evanescent coupling. Such sensors may be configured to measure various materials and may be used to form multi-phase sensing devices.
