In-line Mach-Zehnder interferometer composed of microtaper and long-period grating in all-solid photonic bandgap fiber
We report a compact in-line Mach-Zehnder interferometer combining a microtaper with a longperiod grating (LPG) in a section of all-solid photonic bandgap fiber. Theoretical and experimental investigations reveal that the ...
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 ...
