Abstract
An optical component comprises a metasurface comprising nanoscale elements. The metasurface is configured to receive incident light and to generate optical outputs. The geometries and/or orientations of the nanoscale elements provide a first optical output upon receiving a polarized incident light with a first polarization, and provide a second optical output upon receiving a polarized incident light with a second polarization that is different from the first polarization.
Claims19
An optical component, comprising:
- a metasurface comprising nanoscale elements configured to receive incident light and to generate optical outputs,
- wherein geometries or orientations of the nanoscale elements provide a first optical output upon receiving a polarized incident light with a first polarization, and provide a second optical output upon receiving a polarized incident light with a second polarization that is different from the first polarization,
- wherein the nanoscale elements comprise a plurality of pillars, wherein at least one adjacent pillar of the plurality of pillars has a different angle of rotation and width from the other adjacent pillar.
