Fast and Large-range Frequency-hopping mm-wave Signal Transmission System Based on Direct Modulation Laser

We proposed and experimentally demonstrated a millimeter wave frequency-hopping signal transmission system. The system can realize fast optical wavelength tuning based on direct modulation laser and millimeter wave frequency-hopping signals generation by optical heterodyning. In experiments, frequency hopping signals with a switching time of 100 us and signals whose carrier frequency hops from 27.5 GHz to 29.7 GHz were successfully received.
