Note unusual time

Spin-orbit coupling of light describes how spin angular momentum of light (associated with circular/elliptical polarization of the electric field) is coupled to orbital angular momentum of light (associated with the energy flow and propagation direction). I will focus on a specific example of “spin orbit coupling” related to electromagnetic evanescent waves which allows controlling the propagation direction of guided light waves simply by tuning the polarization of a point source. This effect is very fundamental, broadband, and robust to imperfections. I will describe the various experimental demonstrations and latest applications which we carried out to test this effect and its reciprocal version.
