Abstract
Light coupling to planar lightwave circuits by means of directional coupling between D-fiber and buried rectangular waveguide is indicated as a viable mean of reducing alignment tolerances in the fiber-pigtailing procedure for integrated optical devices. The geometry involved is that of a circular fiber core vertically coupled to a rectangular buried waveguide. An accurate analysis by a vectorial formulation of the finite element method is presented of such a coupling geometry in collinear configuration. The structure is analyzed for symmetric and antisymmetric cladding configurations. The power coupling efficiency is investigated in terms of waveguide dimensions and refractive index steps.
