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 ...
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 ...
Efficient one-third harmonic generation in highly Germania-doped fibers enhanced by pump attenuation
We provide a comprehensive study on one-third harmonic generation (OTHG) in highly Germania-doped fiber (HGDF) by analyzing the phase matching conditions for the step index-profile and optimizing the design parameters. For ...
