<title>Technology and spectral properties of Bragg gratings written in the fiber taper region</title>

In this paper we present the technology of Bragg grating inscription in tapered telecom fibers. The bibliography of the subject i.e. theories of tapered fibers, Bragg gratings and tapered fiber Bragg gratings as well as up to date experimental experience have been outlined. The applied technologies have been explained in the experimental part of this paper. The results of spectral characteristics of the fabricated tapered fiber Bragg gratings were also presented. Conclusions and further research prospects were given.
