A full-vector modal based on a finite element scheme is formulated for the analysis of optical waveguides and photonic crystal fibers. In order to avoid spurious solutions, an edge/nodal hybrid element is applied and, to investigate the behavior of not only bound modes but leaky modes in optical waveguides, an anisotropic perfectly matched layer (PML) is employed as boundary condition at the edges of the computational The validity and usefulness of this approach is confirmed when a rib anti-resonant reflecting optical waveguide (ARROW) and photonic crystal fibers (PCFs) are taken into account. Furthermore, numerical results shown that confinement loss in PCFs increase with increasing wavelength and it is sharply reduced by adding more ring of air holes to the cladding region.
