ABSTRACT:
Diffraction gratings for coupling an electromagnetic wave into a planar waveguide are disclosed. The diffraction grating may include a first diffraction grating and a second diffraction grating slanted relative to one another. Alternatively, the diffraction grating may include a first diffraction grating and a second diffraction grating spaced apart to form a gap therebetween.
