In this paper, we describe a simulation method to analyze the spectral properties of fiber Bragg gratings written in silica-based multimode graded-index fiber, and compare the simulation results wi…
In this work, we report the inscription of fiber Bragg grating through the over-clad in cyclic transparent fluoropolymer (CYTOP) optical fiber using a phase mask technique and a 400 nm femtosecond …
We report on the thermal regeneration of tilted Bragg gratings (TFBGs) produced in hydrogen loaded SMF-28 optical fiber using two types of UV lasers: 266 nm femtosecond pulses and 193 nm nanosecond…
