<title>High birefringent photonic crystal optical fiber for Bragg gratings inscriptions</title>

Abstract

Paper presents technology manufacturing and basics parameters of photosensitive high birefringent photonic crystal fiber made from high silica glasses. It was especially elaborated for Bragg gratings inscriptions. Common photonic optical fibers have cores made from nondoped silica glasses. Therefore Bragg gratings inscriptions are difficult or impossible. In photosensitive photonic optical fibers cores are made from germanium doped silica glasses. In presented fiber core glass was made with MCVD method. Technology of manufacturing of high birefringent photonic crystal fibers are analogous to technology of manufacturing of common low birefringent holey fibers.
