Wavelength independent all-fiber angle-tunable polarization rotator based on geometric effects

Abstract

We propose and demonstrate a simple wavelength independent all-fiber polarization rotator based on purely geometric effects. The device rotates the orientation of an arbitrary input polarization state by arbitrary angle without changing other parameters of the polarization state. The device structure maintains inherent wavelength independence during the tuning process when a non-birefringent single-mode fiber is used. (C) 2016 Optical Society of Americ
