Photospin state selectrivity, manipulation and storage in photonic structures. Photo-spintronics

Open Access Open Access

Abstract

We show that inclusion of nonlocality in the constitutive relations in photonic cystals has important repercussions in the polarization state behaviour of their electromagnetic modes; in the case of the optical activity, the primary manifestation of nonlocality, these can be related to a photospin-orbit coupling interaction analogous to the electron spin-orbit interaction in asymmetric semiconducting compounds with implications in photo-spin transport and photo-spintronics analogous to those conceived in electron spintronics.
