摘要
The present invention provides a waveguide coupler, comprising: a substrate; two waveguides (25,26) formed on said substrate intersecting at a right angle; and a diffraction grating structure (19) formed at the intersection of said waveguides. ??It is an advantage of the present invention that a polarisation splitter is obtained, which couples orthogonal modes from a single-mode optical fibre into identical modes of two planar waveguides. It may be used in a polarisation diversity configuration to implement a polarisation insensitive photonic integrated circuit based on diffraction grating structures, such as photonic crystals. IMAGE
