100 Tbit/s free-space data link enabled by three-dimensional multiplexing of orbital angular momentum, polarization, and wavelength

Huang, H. et al. (2014) 100 Tbit/s free-space data link enabled by three-dimensional multiplexing of orbital angular momentum, polarization, and wavelength. Optics Letters, 39(2), p. 197. (doi: 10.1364/OL.39.000197) (PMID:24562105)

Abstract

We investigate the orthogonality of orbital angular momentum (OAM) with other multiplexing domains and present a free-space data link that uniquely combines OAM-, polarization-, and wavelength-division multiplexing. Specifically, we demonstrate the multiplexing/demultiplexing of 1008 data channels carried on 12 OAM beams, 2 polarizations, and 42 wavelengths. Each channel is encoded with 100  Gbit/s quadrature phase-shift keying data, providing an aggregate capacity of 100.8  Tbit/s (12×2×42×100  Gbit/s).
