Sb₂S₃/AlGaAs-based reconfigurable metasurface for dynamic polarization and directionality control of quantum emitter emission.

ABSTRACT: In this article, we report, to the best of our knowledge, for the first time, phase change material (PCM)-based reconfigurable metasurfaces for tailoring different degrees of freedom (DoF) of the quantum emitter (QE) emission, namely polarization and directionality, two key controlling factors in applications such as quantum computing, communication, and chiral optics. We have used a hybrid plasmon-QE coupled bullseye grating system utilizing the unexplored concept of composite nano-antennas in quantum photonics as the basic building block of the structures. Carefully engineered azimuthal width profile of the Sb₂S₃/AlGaAs composite ridge and selectively controlled transition of PCM (Sb₂S₃) states provide dynamic control over the amplitude and pha
