Abstract
The planar waveguide Bragg lens and a component utilizing a planar waveguide Bragg lens with a greater acceptance angle characterized by several grating structures being arranged in series and having an inclination towards one another for varying angles of incidence. In one embodiment, each of the grating structures are circular arc segments which are interconnected together to form a single grating structure having curved segments which also has a greater acceptance angle than a conventional planar waveguide Bragg lens.
