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.
Abstract:
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.
Abstract:
Techniques for coupling optical energy between a side-polished port of a fiber in one substrate and a coupling port of a waveguide in another substrate.
Abstract:
Fiber optical devices formed on substrates fabricated with grooves that operate based on evanescent optical coupling through a side-polished fiber surface in each fiber involved.
Abstract:
Optical Mach-Zehnder interferometers and related devices, systems that have at least one fiber integrated or engaged to a substrate fabricated with one or more grooves.
Abstract:
Fiber optical devices formed on substrates fabricated with grooves that operate based on evanescent optical coupling through a side-polished fiber surface in each fiber involved.
Abstract:
Fiber optical devices formed on substrates fabricated with grooves that operate based on evanescent optical coupling through a side-polished fiber surface in each fiber involved. An index-changing liquid is used to control the evanescent optical coupling in response to a control signal.
Abstract:
Thin-film techniques in forming fiber devices that engage fibers to a substrate with different material properties. Structure buffering, diffusion bonding, and thickness monitoring may be achieved by such thin-film techniques.
