60 GHz broadband free-space communication using dual-wavelength photonic signal generation

Summary form only given, as follows. A 60 GHz free-space communication system is demonstrated with broadband data encoding and a novel photonic millimeter-wave carrier generator. The 60.8 GHz carrier signal is generated by photomixing two optical subcarriers sourced from a dual-wavelength laser based on stimulated Brillouin scattering in optical fiber. Data rates of 1.65 Gbps are demonstrated. An 30 m indoor and 78 m building-to-building communication link are demonstrated with good bit-error ratios.
