Transmission of a 73.7 Tb/s (96 x 3 x 256-Gb/s) DP-16QAM mode-division-multiplexed signal over 119 km of few-mode fiber transmission line incorporating an inline multi mode EDFA and a phase plate based mode (de-)multiplexer is demonstrated. Data-aided 6 x 6 MIMO digital signal processing was used to demodulate the signal. The total demonstrated net capacity, taking into account 20% of FEC-overhead and 7.5% additional overhead (Ethernet and training sequences), is 57.6 Tb/s, corresponding to a spectral efficiency of 12 bits/s/Hz.

We experimentally verify the advantage of employing advanced coding schemes such as space-time coding and 4 dimensional modulation formats to enhance the transmission performance of a 3-mode transmission system. The performance gain of space-time block codes for extending the optical signal-to-noise ratio tolerance in multiple-input multiple-output optical coherent spatial division multiplexing transmission systems with respect to single-mode transmission performance are evaluated. By exploiting the spatial diversity that few-mode-fibers offer, with respect to single mode fiber back-to-back performance, significant OSNR gains of 3.2, 4.1, 4.9, and 6.8 dB at the hard-decision forward error correcting limit are demonstrated for DP-QPSK 8, 16 and 32 QAM, respectively. Furthermore, by employing 4D constellations, 6 × 28Gbaud 128 set partitioned quadrature amplitude modulation is shown to outperform conventional 8 QAM transmission performance, whilst carrying an additional 0.5 bit/symbol.

24.3GBaud 32QAM WDM transmission over a novel 1km hole-assisted few-mode multi-core fiber is demonstrated, resulting in 5.1Tbit/s spatial supercarriers (4Tbit/s net) with a gross spectral efficiency of 102bits/s/Hz, and a gross aggregate transmission rate of 255 Tbit/s (200 Tbit/s net).

We report for the first time coherently-detected, polarization-multiplexed transmission over photonic band gap fiber. By transmitting 96 × 320-Gb/s DP-32QAM modulated channels, a net data rate of 24 Tb/s was obtained.

We demonstrate the codesign and cointegration of an ultracompact silicon photonic receiver and a low-power-consumption (155 mW/channel) two-channel linear transimpedance amplifier array. Operation below the forward error coding (FEC) threshold both for quadrature phase-shift keying (QPSK) and 16-quadrature amplitude modulation (QAM) at 28 Gbaud is demonstrated.

Channel state information (CSI) of transmission systems is important for mode dependent loss (MDL) estimation. Using the heuristic minimum mean square error method, we show MDL estimation within 0.3dB with respect to the least-squares method.

Experimental demonstration of an 8-state (Turbo-) Trellis-coded modulation achieving a data throughput of 2 bits/symbol is demonstrated. TTCM outperforms Quadrature Phase Shift Keying with an OSNR gain of 3.8 dB after 1000 km at HD-FEC.

Conventionally, an SDM system requires a 4-port oscilloscope for each dual polarization mode. Using a novel and cheaper 2×4-port oscilloscope SDM receiver, 3-mode 28GBaud DP-32QAM is experimentally verified after 41.7km few-mode fiber transmission.
