Abstract

We present results of Bragg gratings inscription in several crystalline optical weveguiding structures. Using infrared femtosecond radiation and the phase mask method, Bragg gratings were inscribed in multimode crystalline sapphire fiber, RPE lithium niobate waveguides and large area core multimode YAG fibers. It was shown that Bragg grating structures could be created in all these crystalline substrates with comparable IR- intensities. The spectral characteristics and the thermal stability of these Bragg gratings is also presented.
