Interconversion of orbital and spin angular momenta of light beams in the sum-frequency generation process from the surface of the isotropic chiral medium

摘要

We study the interaction between spin and orbital components of the angular momentum of electromagnetic waves in the sum-frequency generation process on a surface of the nonlinear isotropic chiral medium within undepleted pump approximation. Both bulk and near-surface responses of the medium are taken into account. Classical and quantum explanations of particular features of three-wave mixing on the surface of a nonlinear medium are presented. (C) 2020 Optical Society of America
