“…1 In addition to the multiplexing technologies based on amplitude, wavelength [2][3][4] and light polarization 5,6 division, the orbital angular momentum (OAM) of optical vortex (OV) beams [7][8][9][10][11] provides a new degree of freedom for multiplexing to further increase the capacity of optical communications systems. OV beams have helical phase profiles in their electric fields that are proportional to the azimuthal phase term of exp(i'w), where ' is the eigenvalue of the OAM or the so-called topological charge and w is the azimuthal angle.…”

Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods. Orbital angular momentum (OAM) in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems, with OAM beams acting as information carriers for OAM division multiplexing (OAM-DM). We demonstrate independent collinear OAM channel generation, transmission and simultaneous detection using Dammann optical vortex gratings (DOVGs). We achieve 80/160 Tbit s 21 capacity with uniform power distributions along all channels, with 1600 individually modulated quadrature phase-shift keying (QPSK)/16-QAM data channels multiplexed by 10 OAM states, 80 wavelengths and two polarizations. DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s 21 level.

“…Spectrally-efficient modulation formats are currently receiving significant attention for next-generation high-capacity optical communication systems [1][2][3]. With information encoded on both the amplitude and phase of the optical carrier for M-ary quadrature amplitude modulation (QAM), accurate measurement analysis needs to be developed to quantify the novel modulation schemes and to reliably predict the performance of optical coherent systems.…”

This paper presents the estimation of bit error ratio (BER) from error vector magnitude (EVM) for M-ary quadrature amplitude modulation (QAM) formats in optical coherent systems employing carrier phase recovery with differential decoding to compensate for laser phase noise. Simulation results show that the relationship to estimate BER from EVM analysis for data-aided reception can also be applied to nondata-aided reception with a correction factor for different combined linewidth symbol duration product at the target BER of 10 −3 . It is demonstrated that the calibrated BER, which would otherwise be underestimated without the correction factor, can reliably monitor the performance of optical coherent systems near the target BER for quadrature phase shift keying (QPSK), 16-QAM, and 64-QAM.
