Abstract
Twisted single photons, carrying orbital angular momentum (OAM), could address the growing demand for high-dimensional quantum information encoding and transmission. By hybrid integration of two-dimensional semiconductor WSe2 with a spin-orbit-coupled microring resonator, we demonstrate a twisted single photon source with the ability to precisely define and switch between highly pure spin-OAM states.
