Radio-over-fiber transmission using vortex modes [PDF]
2015 International Topical Meeting on Microwave Photonics (MWP), 2015 This paper demonstrates experimentally the distribution of radio-over-fiber (RoF) signals using orbital angular momentum (OAM) of light over standard OM4 multimode fiber (MMF) at 850 nm wavelength. Five independent OAM modes are used to convey RoF signals in the microwave regime showing robust performance and therefore opening new prospects for ...
