Abstract

This paper describes a gradient-index planar waveguide (GIPW) coupler, its design and, structure in detail, and carefully analyzes its operating principle. Because mode-dimension and emission-angle of a semiconductor optical amplifier (SOA) can be converted with a selected direction by a gradient-index planar waveguide coupler, a high-efficiency fiber-chip coupling application is realized. The minimum coupling loss is less than 3dB.The gradient-index planar waveguide coupler can be used to replace a cylindrical lens sometimes due to their equivalent optical properties.
