Abstract

Polarization maintaining fiber with a near rectangular cross section, made by preform deformation, has demonstrated extinction ratios for 5 meter lengths of 43 dB, h parameter values of 1.7x10^-6 m^-1 for 100 meter lengths and losses of 0.8 dB/km at 1.3 and 1.5ttm. Polarizing fiber with a W type index profile, also made by preform deformation, has demonstrated extinction ratios of greater than 30 dB in straight lengths as short as 5 cm. with orthogonal polarization cutoff wavelengths separated by 0.1μm and insertion loss of less than 3 dB. The rectangular shape of these fibers facilitates location of the principal axes and allows winding such that a principal axes can be aligned with the bending plane.
