Various embodiments of the present invention are directed to optical devices comprising planar lenses. In one aspect, an optical device includes two or more planar lenses, and one or more dielectric layers. Each planar lens includes a non-periodic, sub-wavelength grating layer, 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 so that light transmitted through the optical device substantially parallel to the optical axis is refracted by the two or more planar lenses.

Optical devices based on non-periodic sub-wavelength gratings

Various embodiments of the present invention are directed to optical devices comprising planar lenses. In one aspect, an optical device includes two or more planar lenses (), and one or more dielectric layers (-). Each planar lens includes a non-periodic, sub-wavelength grating layer (), 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 () so that light transmitted through the optical device substantially parallel to the optical axis is refracted by the two or more planar lenses.

Embodiments of the present invention are directed to multiplexer/demultiplexer systems. In one aspect, a multiplexer/demultiplexer system includes an input/output waveguide, two or more output/input waveguides, and a planar, non-periodic, sub-wavelength grating. The grating is configured so that when the system is operated as a multiplexer, each wavelength of light output from one of the two or more output/input waveguides is reflected by the grating toward the input/output waveguide. When the system is operated as a demultiplexer, each wavelength of light output from the input/output waveguide is reflected toward one of the two or more output/input waveguides.
