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 ...
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 ...
