Analysis Of Highly Birefringent Photonic Crystal Fibers With Squeezed Rectangular Lattices
In this article, we analyze the birefringence of photonic crystal fibers with squeezed rectangular lattices by using finite element method. When the original photonic crystal fiber is squeezed, the lattice is compressed, and the holes become elliptical. This operation leads to birefringences as high as 7.5 × 10-3 at 1550 nm. However, confinement losses and dispersion are also changed after this operation is performed, needing to be reassessed. We estimate the changes in dispersion and...[Show more]
