Simultaneous and Quantitative Spin and Orbital Angular Momentum Detector

We design a simultaneous and quantitative spin and orbital angular momentum (SAM/OAM) detector, which is rather compact only with orthogonal nanoslit pairs etched on a silver film. Based on the surface plasmon polariton wave excited on this device surface, SAM of ±1 can be distinguished according to...
