Singular-Phase Optical Sensing with Topologically-Protected Tamm Interfacial States in Planar Nanostructures
We demonstrate an ultra-thin planar perfect absorber based on the excitation of a topologically-protected interfacial optical state and test its performance as a sensitive optical sensor in both the amplitude and phase detection schemes.
