Published in 2020 at "Advanced Optical Materials"

DOI: 10.1002/adom.201901800

Abstract: Circular polarization discrimination is desired for use in many optoelectronic applications. By integrating asymmetric metamaterials with active materials, circular‐polarization‐discriminative light–matter interaction can be realized. Nevertheless, the circular polarization extinction ratio for absorption of the active… read more here.
