This investigation elucidates the refractive index-change response of the photosensitive optical fiber to exposed UV flux. The nonlinear UV photosensitivity deforms the index profile of FBGs on the tail edges where the writing UV flux is low. Pre-UV

In this study, we propose a novel equivalent-waveguide concept to design the completely adiabatic tapered waveguides. The optimal combination of taper shape and refractive-index distribution in such ideal structures is obtained by applying a series o
