Multi-zone flat-optics architectures, systems and methods

Abstract

Flat optics systems, architectures, and methods that incorporate multi-zone design for enhanced performance and multifunctionality. The flat optics technology incorporates metasurfaces to leverage the pixelated, planar device architecture to integrate additional features such as beam shaping, modulation, testing, alignment, and adaptive functionality on a single platform, offering superior performance and small form factor. A disclosed multi-zone flat optical device includes multiple flat optics components such as metasurfaces formed on or in a substrate, forming primary and auxiliary functional zones, where the primary functional zone performs a primary optical function, and the primary functional zones are used for testing, alignment, calibration, recognition, etc. The multiple functional zones may be configured to operate under different incident light conditions including wavelength, incident angle, polarization, etc. so that the operation of the auxiliary functional zones does not interfere with the operation of the primary functional zone. Fabrication and assembling methods are also disclosed.
