Abstract

Controlling optical spins and pseudospins carried by electromagnetic guided waves can find many applications in the fields of spintronics and valleytronics, supporting efficient information transport using these degrees of freedom. In this work, we explore the general opportunities offered by metasurfaces to route optical momentum, spin and helicity by coupling to guided surface waves. We show how tailoring anisotropy and bianisotropy yields extreme directionality when coupled to the spin of localized sources. In-plane circularly polarized excitations are particularly important in this context when considering 2D excitonic materials. They offer specific challenges when coupled to metasurfaces, addressed here with suitably engineered nonlocality and nonreciprocity.
