Creation of Orbital Angular Momentum States with Chiral Polaritonic Lenses
Creation of Orbital Angular Momentum States with Chiral Polaritonic Lenses
Controlled transfer of orbital angular momentum to an exciton-polariton Bose-Einstein condensate spontaneously created under incoherent, off resonant excitation conditions is a long-standing challenge in the field of microcavity polaritonics. We demonstrate, experimentally and theoretically, a simple and efficient approach to the generation of nontrivial orbital angular momentum states by using …
