Experimentation of Fiber-Optic Transmission of Light with Orbital Angular Momentum

摘要

The fiber-optic transmission of Laguerre-Gaussian photons carries the potential for removing the inconvenience of alignment and space required in free-space experimentation while introducing a severity of power loss caused by coupling inefficiency as the profile propagates through the fiber-optic components. This experimentation was planned to gain some insight into the behavior of the Laguerre-Gaussian profile when transmitted through fiber-optic channels in order to have the ability to set up a quantum system which is part free space and part fiber-optic since the LG-profiles have to be created in free space. The free space research on computer generated holograms for profile generation, liquid crystal retarders for modulation of the absolute phase, the Mach-Zehnder interferometer and the orbital angular momentum sorter as well as the Spatial Light Modulator for the work under the senior fellowship continued side-by-side during the summer, while waiting for the equipment because all of these are going to contribute to the overall quantum information (QI) research at the Air Force Research Laboratory at Rome, NY.
