摘要：

An optical coupling mount for use in coupling light between a semiconductor waveguide device and an optical fibre comprises a silica based spot size converter () located on an optical bench () with a trench () and grooves (), whereby the semiconductor device () can be positioned in close alignment with the spot size converter (). The spot size converter () comprises a tapered upper waveguide () located above a non-tapered lower waveguide (). The dimensions of the spot size converter () are such that a semiconductor device emitting a small, astigmatic optical beam can be efficiently coupled to a single mode fibre requiring a larger, concentric beam.
