Waveguide sensors having a side-polished coupling port at the waveguide cladding to sense a material based on material-specific optical attenuation by evanescent coupling at the coupling port.

Optical multiphase flow sensor

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.

Sensing devices based on evanescent optical coupling

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.

Reflection-mode fiber sensing devices

Adjustable filters formed in fibers or waveguides based on evanescent coupling, where a coupling layer is formed between a waveguide overlay and a side-polished coupling port on the fiber or waveguide. A control mechanism may be provided to adjust a property of at least one of the waveguide overlay and the coupling layer to adjust the output of the filter.
