Low Noise and Drift Reconfigurable Solution-Processed Chalcogenide Phase Change Metasurfaces.

ABSTRACT: Chalcogenide glasses are increasingly favoured as the programmable layer of choice in reconfigurable optoelectronic platforms, enabling diverse signal modulation, display, and memory device applications over the past decade. These applications capitalize on the amorphous-to-crystalline phase transition of these alloys, often produced using expensive ultrahigh-vacuum physical vapor deposition (PVD) methods. Here, a cost-effective, solution-processed approach is presented to synthesizing chalcogenide phase change materials (PCMs). Our results show that optical-grade antimony sulfide (Sb₂S₃) can be deposited onto various substrates at subwavelength thicknesses. Notably, these films demonstrate non-volatile phase change modulation contrasts comparable to PVD methods, with
