Paper Abstract

Under the paraxial approximation for the propagation of vectorial coherence function, we made a theoretical investigation into the mechanism of the orbital angular coherence momentum associated with a coherence vortex. By controlling the irradiance distribution of an extended quasi-monochromatic spatially incoherent source with a spatial light modulator, we examined the phase structure of coherence function and investigated the birth and evolution of the orbital angular coherence momentum. Some properties related to the fractional coherence vortex, such as a wave particle-like duality of coherence function, are also investigated both theoretically and experimentally for the first time.
