Comparison of the properties among photonic crystal fibers with different elliptical inner cladding configuration

Some kinds of high birefringence photonic crystal fibers (PCFs) with elliptical inner cladding are analyzed by Galerkin finite element method with transparent boundary conditions (TBC). Several properties of them, such as the birefringence, confinement loss and dispersion are deduced and compared .It is shown that PCFs with different elliptical inner cladding formed by enlarging or diminishing air holes have different properties. High birefringence can be obtained through intruding the difference of air holes size along orthogonal direction. Enlarged air holes reduce the CL, and increase the dispersion and dispersion slope; but diminished air holes is reversed.
