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 ...

Scientists have cracked a century-old physics mystery by detecting magnetic signals in non-magnetic metals using only light ...

We design, fabricate and demonstrate chip-scale inverse-designed multimode meta-waveguides to generate OAM beam. By experimental measurement, eight kinds of optical vortex beams can be generated in ...
