Abstract
A light source is coupled to an input facet that directs light from the light source to a core layer of a waveguide and a gradient index material layer disposed beside the core layer along a portion of a propagation length of the waveguide. Light is launched from the light source into the input facet. In response, the gradient index material layer directs light to the core layer at least along the portion of the propagation length.
