Abstract:
Metasurface elements, integrated systems incorporating such metasurface elements with light sources and/or detectors, and methods of the manufacture and operation of such optical arrangements and integrated systems are provided. Systems and methods for integrating transmissive metasurfaces with other semiconductor devices or additional metasurface elements, and more particularly to the integration of such metasurfaces with substrates, illumination sources and sensors are also provided. The metasurface elements provided may be used to shape output light from an illumination source or collect light reflected from a scene to form two unique patterns using the polarization of light. In such embodiments, shaped-emission and collection may be combined into a single co-designed probing and sensing optical system.

Claim (Index 1):
A method for fabricating one or more metasurface elements or systems comprising:\n depositing a hard mask material layer on at least one surface of a substrate, wherein the substrate is transparent to light over a specified operational bandwidth; depositing a pattern material layer on the hard mask material layer; patterning the pattern material to form an array pattern atop the hard mask layer, the array pattern comprising one of either a positive or negative reproduction of a metasurface feature array, the metasurface feature array comprising a plurality of metasurface features having feature sizes smaller than the wavelength of light within the specified operational bandwidth and configured to impose a phase shift on impinging light within the plane of plurality of metasurface features; etching the hard mask layer using an anisotropic etch process to form a plurality of voids and raised features corresponding to the array pattern in the hard mask; and removing any residual pattern material from atop the hard mask layer.
