Multiplexed optical sensing using topological phase singularities in anisotropic borophene ultrathin films
Abstract
Phase singularities (PSs) of topological darkness have garnered substantial attention in the realms of bio-sensing, single-molecule label-free sensing, and super-resolution imaging, owing to their remarkable characteristics such as ultra-sensitivity, label-free detection capabilities, and robustness against structural defects. Nevertheless, the implementation of multiplexed singular-phase configurations within the topological sensing system is not only essential but also presents formidable challenges, primarily due to the requirement of achieving absorption at specific frequencies. To surmount this obstacle, we conduct a theoretical investigation on a structure comprising a silver substrate, a deposited ultra-thin ( h
