Over 100 Gb/s Ultrabroadband MIMO Wireless Signal Delivery System at the D-Band

We propose and experimentally demonstrate an ultrabroadband wireless millimeter-wave (mm-wave) signal delivery system at the D-band (110-170 GHz), employing the techniques of photonics-aided mm-wave generation, wireless multiple-input multiple-output (MIMO), and high-level vector signal modulation, combined with digital heterodyne coherent detection. Our demonstrated system not only can deliver up to 46-Gbaud (184-Gbit/s) polarization-division-multiplexing quadrature-phase-shift-keying (PDM-QPSK) signal over 80-km single-mode fiber-28 (SMF-28) and 0.6-m 2 × 2 MIMO wireless link at the D-band but can deliver up to a 16-Gbaud (128-Gbit/s) polarization-division-multiplexing 16-ary quadrature-amplitude-modulation (PDM-16QAM) signal over 10-cm 2 x 2 MIMO wireless link at the D-band as well. To the best of our knowledge, we have realized a record bit rate of 184 Gbit/s for the D-band wireless mm-wave signal delivery.
