Double topological phase singularities in highly absorbing ultra-thin film structures for ultrasensitive humidity sensing

Phase singularities (PSs) in topological darkness-based sensors have received significant attention in optical sensing due to their rapid, ultra-sensitive, and label-free detection capabilities. Here, we present both experimental and theoretical investigations of an ultrasensitive and multiplexed ph...
