Rigorous analysis of the optical rib-guide using rectangular waveguide modes
Abstract
The propagation constants of the two fundamental modes of a symmetrical rib guide are calculated by means of mode expansions into eigenmodes of the rectangular dielectric loaded waveguide. The delay difference between the modes is determined, and the conditions for single-mode operation are given. The results are compared with known approximations.
