Abstract

Several types of fiber polarizers have been proposed [1]-[4]. Most of them utilize the difference in bending loss between two orthogonally polarized modes [3][4]. However, the single polarization bandwidths of the conventional fiber polarizers are not wide enough to meet the operation wavelength specifications in practical use. Currently, we have developed the ultra-wide bandwidth fiber polarizer as an attractive component of fiber optic sensing systems. This paper describes characteristics of the fiber polarizer with the widest single polarization bandwidth over 320nm around 840nm wavelength, reported so far.
