An All-Dielectric Metasurface Polarimeter. [PDF]
ACS Photonics, 2022 We demonstrate an all-dielectric meta-polarimeter with a single unit-cell design capable of direct measurement of any arbitrary polarization states, achieving a polarization-measurement fidelity of 99 ± 1%. This holds promise for ultra-compact polarization imaging and quantum state tomography.

All-dielectric metasurface circular dichroism waveplate. [PDF]
Sci Rep, 2017 AbstractWe propose and experimentally demonstrate a high efficient circularly polarizing dichroism waveplate (CPDW) using a Si-based all-dielectric 2Dchiral metasurface. We demonstrate that the CPDW exhibits a unique dichroism in that it functions as a transmissive quarter waveplate for one of either left-or right-handed circularly polarized incident ...
