摘要： Planar reflective devices that operate as reflective blazed diffraction gratings are disclosed. In one aspect, a reflective device includes a substrate with a planar surface, and a planar, high-contrast, sub-wavelength grating disposed on the surface. The grating is divided into a number of regions that each reflect incident light of a particular wavelength and with a particular angle of incidence into a single diffraction order and associated diffraction angle.

In one aspect, an optical device includes two or more planar lenses (208,209), and one or more dielectric layers (210-212). Each planar lens includes a non-periodic, sub-wavelength grating layer (1110), and each dielectric layer is disposed adjacent to at least one planar lens to form a solid structure. The two or more planar lenses are substantially parallel and arranged to have a common optical axis (214) so that light transmitted through the optical device substantially parallel to the optical axis is refracted by the two or more planar lenses.

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.
