Ultrathin high-performance circular polarizers based on MoOCl2/NbOCl2 van der Waals heterostructures

Circularly polarized light (CPL) holds immense promise for diverse applications, including 3D displays, quantum information processing, biosensing, and optical imaging. However, high-performance, ultrathin, and easily integrable devices for CPL manipulation and discrimination rem...

Encapsulated CsPbBr3 quantum dots with asymmetric chiral magneto-optoelectronic responses

Quantum emitters having non-trivial spin polarizations are highly demanded for chiral quantum devices and quantum photonic technologies. Here we investigate the magneto photoluminescence spectroscopy of perovskite quantum dots encapsulated in silica and report an observation of c...
