Abstract
Paper described fabrication methods of high birefringence index guided holey fibers made from silica and high silica glasses. Several kinds of high birefringence holey fibers are described in the point of view their fabrication technology and basic characterization. There are: triple defect fiber with shape induced birefringence, two kinds of fibers with filling factor asymmetry induced birefringence, fibers with filling factor asymmetry induced birefringence and germanium doped core designed for Bragg gratings writing, fiber with filling factor asymmetry induced birefringence and neodymium doped core designed for fiber amplifiers and lasers, dual core fiber with circular and weakly separated cores. Methods of manufacturing we used were: MCVD method for silica and high silica glass preparation as optical fiber preform manufacturing and OVD method for porous silica glass fabrication including additional processes as hydroxylation, impregnation with suitable salts solutions, thermal decomposition, dehydroxylation and sintering lead to silica, high silica and rare earth doped glass preparation in the form of elements for microstructured fiber preforms compose.
