英文摘要	National Natural Science Foundation of China (NSFC) [11104233]; Fundamental Research Funds for the Central Universities [2011121043, 2012121015]; Doctoral Fund of the Ministry of Education of China [2011012112003]; program for New Century Excellent Talents in University of China [NCET-13-0495]; The efficient separation of the orbital angular momentum (OAM) is essential to both the classical and quantum applications with twisted photons. Here we devise and demonstrate experimentally an efficient method of mimicking the Faraday rotation to sort the OAM based on the OAM-to-polarization coupling effect induced by a modified Mach-Zehnder interferometer. Our device is capable of sorting the OAM of positive and negative numbers, as well as their mixtures. Furthermore, we report the first experimental demonstration to sort optical vortices of noninteger charges. The possibility of working at the photon-count level is also shown using an electron-multiplying CCD camera. Our scheme holds promise for quantum information applications with single-photon entanglement and for high-capacity communication systems with polarization and OAM multiplexing.
