摘要： Embodiments of the present invention relate to planar optical devices composed of one or more sub-wavelength diffraction grating layers. In one embodiment, an optical device includes a first substantially planar reflective structure (104,1904), a second substantially planar reflective structure (106,1906), and a substantially planar sub-wavelength grating layer (102,1902) disposed between the first reflective structure and the second reflective structure. The grating layer is configured with lines (208-211,214-217) having line widths, line thicknesses, and line period spacing selected to control phase changes in different portions of a beam of light transmitted through the optical device.

摘要： Planar, polarization insensitive, optical elements to control refraction of transmitted light in free space are disclosed. In one aspect, an optical element includes a substrate having a planar surface, and a polarization insensitive, high contrast, sub-wavelength grating composed of posts that extend from the planar surface. The grating has at least one region. Within each region, cross-sectional dimensions of the posts and/or lattice arrangement of the posts are nonperiodically varied to control refraction of light transmitted through the optical element.

摘要： Aspects of the present invention are directed to flat sub-wavelength dielectric gratings that can be configured to operate as mirrors and other optical devices. In one aspect, a grating layer (102) has a planar geometry and is configured with lines (206,207). The lines widths, line thicknesses and line period spacings (208) are selected to control phase changes in different portions of a beam of light reflected from the grating such that the phase changes collectively produce a desired wavefront shape in the beam of light reflected from the grating.

摘要： A vertical cavity surface emitting laser (VCSEL) system and method of fabrication are included. The VCSEL system includes a first portion comprising a first mirror and a gain region to amplify an optical signal in response to a data signal, the first portion being fabricated on a first wafer. The system also includes a second portion comprising a second mirror that is partially-reflective to couple the optical signal to an optical fiber. The second portion can be fabricated on a second wafer. The system further includes a supporting structure to couple the first and second portions such that the first and second mirrors are arranged as a laser cavity having a predetermined length to resonate the optical signal.
