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.

Abstract: Meta-surface devices may be advantageously used for miniaturization, planar and thin film, high spatial resolution, and dense integration into optical devices. They have the potential to be used for steering a beam propagation direction, shaping wave-front light, and imparting information for application such as sensing, imaging, light detection, and ranging. However, meta-surface devices may have poor overall efficiency when compared with traditional optical devices. Embodiments of this disclosure relate to meta-surface devices including a pattern of high-index pillars with a low-index coating. Advantageously, the low-index coating may improve optical efficiency of the meta-surface devices which may make these meta-surface devices suitable for a variety of applications.

Abstract: Disclosed herein are single element dot pattern projectors with a meta-optics. The projectors include a laser light source and a metasurface chip integrated onto the laser light source. The metasurface chip includes metasurface elements spaced apart from the laser light source by a distance equal to the collimating function focal length of the metasurface chip. the laser light source produces light which is diffracted through the metasurface elements to produce a dot pattern. Projectors enabled by meta-optics lead to unique methods of integrating the meta-optic and unique functionality that can be added to the dot pattern.
