US Patent:

20200271941, Aug 27, 2020

Filed:

May 13, 2020

Appl. No.:

15/931184

Inventors:

- Weston MA, US
Robert Devlin - Abington PA, US
Adam Erlich - Arlington MA, US
Pawel Latawiec - Allston MA, US
John Graff - Swampscott MA, US

Assignee:

Metalenz, Inc. - Weston MA

International Classification:

G02B 27/09
H01L 27/146

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.
