Abstract:
A grating-coupled light guide includes a plate light guide and a grating coupler at an input to the plate light guide. The grating coupler is to receive light from a light source and to diffractively redirect the light into the plate light guide at a non-zero propagation angle as guided light. Characteristics of the grating coupler determine a spread angle of the diffractively redirected guided light.
