Paper Abstract

The technology of Bragg grating formation in tapered regions of telecom fibers is presented. Spectral properties of such Bragg gratings were measured. The tapers were made by thermal heating in the oxy-butane flame. The tapers were kept later in the high pressure hydrogen chamber to enhance the glass photosensitivity. Bragg gratings were formed in the taper region using interferometric pattern using the argon-ion laser 244nm illumination. The transmission spectral characteristics of such gratings show chirp effect. Such advanced devices will be applied as sensors combining the behavior of exposed modal field in the tapers and Bragg gratings properties.
