60 Gbit/s 400 GHz wireless transmission

We experimentally demonstrate a 400 GHz carrier wireless transmission system with real-time capable detection and demonstrate transmission of a 60 Gbit/s signal derived from optical Nyquist channels in a 12.5 GHz ultra-dense wavelength division multiplexing (UD-WDM) grid and carrying QPSK modulation. This is the highest data rate demonstrated for carrier frequencies above 300 GHz and also validates the feasibility of bridging between next generation 100 GbE wired data streams and indoor wireless applications.
