Pre-equalization technique enabling 70 Gbit/s photonic-wireless link at 60 GHz

In this paper, we demonstrate a 70 Gbit/s photonic-based wireless link at 60 GHz using a single RF carrier and a single polarization. This high capacity is achieved by using 32QAM modulation with a symbol rate of 14 GBd. We show a novel pre-equalization technique that enables usage of such very high bandwidths at 60 GHz. Our work indicates that the consumer oriented 60 GHz band could be a viable alternative to more expensive E-band or sub-THz links for high capacity photonic wireless transmission, mobile backhauling and last-mile high-capacity connections.
