A full-vectorial method for efficient holey optical fiber modeling

Summary form only given. We propose a full-vectorial algorithm, which solves the wave equations exactly, without the assumption of de-coupling of the two transverse fields. The algorithm based on Hermite-Gaussian function expansions is efficient because only relatively few terms are necessary to obtain good results. Our algorithm simplifies the refractive index representation, is better suited to various holey fiber structures, and provides better approximations around the core region. Compared with previous studies, our proposed algorithm considers both transverse field components, and is an accurate modeling for strongly guiding structures like holey fibers. The full-vectorial algorithm has been checked against analytical results in analytically solvable structures, and experimental results. Very good agreement is obtained in both cases.
