Novel optical fast fourier transform scheme enabling real-time OFDM processing at 392 Gbit/s and beyond

Novel optical fast fourier transform scheme enabling real-time OFDM processing at 392 Gbit/s and beyond

An optical FFT scheme is implemented and tested at 392 Gbit/s. It enables OFDM signal processing way beyond the bandwidth limits of electronics. The scheme operates with little energy as it exploits passive optical components.
