摘要： Embodiments of the present invention are directed to planar sub-wavelength dielectric gratings that can be configured to control the beam profile of reflected and transmitted light. In one embodiment, a grating (200) includes a planar structure having a first surface and a second surface located opposite the first surface. The grating includes a non-periodic grating (201-203,210,212,216,218) formed within the first surface. For light incident on the first surface, a first portion of the light is reflected with a first wavefront shape and a first irradiance profile and a second portion of the light is transmitted with a second wavefront shape and a second irradiance profile.
