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 ...
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 ...
