Inscription of superimposed fiber Bragg gratings using a Talbot interferometer

摘要

In this paper, we present results on the inscription of superimposed Bragg gratings in various optical fibers, including specialized light guides produced in Russia, using an inscription setup based on the Talbot interferometer. A KrF excimer laser system of the master oscillator type-an Optosystems CL-7550 power amplifier-is used as the source of ultraviolet radiation for the experimental stand. The spectral characteristics of superimposing a different number of fiber Bragg gratings are demonstrated and the inscription of several Bragg gratings in the same region of the optical fiber is investigated.
