A Mach-Zehnder interferometer by combining a microtaper with a long period grating in an all solid photonic bandgap fiber and its temperature sensing characteristic
We demonstrate a new type of Mach-Zehnder interferometer by combining a nonadiabatic microtaper with a long period grating in the same stage of all solid photonic bandgap fibers. Meanwhile, the mode-coupling caused by the ...
Discrimination between refractive index and temperature by two cascaded cladding-mode type fiber sensors
We demonstrated a fiber sensor for simultaneous measurement of refractive index and temperature by cascading one long period grating and one modal interferometer. Cladding mode interference between them was also ...
Investigation of strain-induced effects on microwave signals from an PM-EDF based short cavity DBR laser
Axial strain-induced effects on beating frequency from a short cavity PM-EDF based distributed Bragg reflector (DBR) laser was investigated and experimentally demonstrated for the first time. A linear strain sensitivity ...
Simultaneous measurement of curvature and strain based on fiber Bragg grating in two-dimensional waveguide array fiber
We report on the fabrication of a fiber Bragg grating (FBG) with multiple resonances in a two-dimensional waveguide array microstructured optical fiber containing 91 cores. Theoretical investigation reveals that these ...
Directional torsion and temperature discrimination based on a multicore fiber with a helical structure
We propose and experimentally demonstrate a directional torsion sensor based on a Mach-Zehnder interferometer formed in a multicore fiber (MCF) with a ~570-μm-long helical structure (HS). The HS was fabricated into the MCF ...
Ultra-sensitive chemical and biological analysis via specialty fibers with built-in microstructured optofluidic channels
All-in-fiber optofluidics is an analytical tool that provides enhanced sensing performance with simplified analyzing system design. Currently, its advance is limited either by complicated liquid manipulation and light ...
