Abstract :
We proposed a novel polarization splitter based on single-polarized elliptical-hole core circular-hole holey fibers (EC-CHFs). We employed the full-vector finite element beam propagation method to demonstrate the polarization splitter which is designed by the large hole EC-CHFs (air filling fraction in core is 36.73%) and small hole EC-CHFs (air filling fraction in core is 4.08%) can completely split an arbitrarily polarized light beam into two orthogonal polarization states without any crosstalk. In addition, we also calculated the tolerance and wavelength dependence of this kind of polarization splitter.
