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 ...
Temperature-independent strain sensor based on simplified hollow-core photonic crystal fibers
In this paper, Mach-Zehnder interference-based fiber sensors is demonstrated on an intermodal interference in the simplified hollow-core photonic crystal fibers (HCPCF) by splicing the HCPCF to single mode fiber (SMF) with ...
