Optical Polarization Sensor Based on a Metalens

, 2022
We investigated an optical microsensor of the polarization state of a laser light based on a metalens. In contrast to known polarization sensors based on metasurfaces that deflect different polarization types using various angles to the optical axis, the

Active magneto-optical metalens

Optics Express
We demonstrate a metasurface made of bismuth-substituted yttrium iron garnet (BIG) nanodisks that, in the presence of a magnetic field, functions as a polarization-sensitive metalens. Specifically, switching the handedness of the incident circularly polarized light (from right- to left-handed or vice versa) results in distinct focusing behavior.

Electrically Driven Varifocal Silicon Metalens [PDF]

, 2018
Optical metasurfaces have shown to be a powerful approach to planar optical elements, enabling an unprecedented control over light phase and amplitude. At that stage, where a wide variety of static functionalities have been accomplished, most efforts are
