    Abstract: Optical systems and methods for transmission of multiple beams and direct detection of those beams are described. One transmitter for use in a free space optical communication system includes a broad spectrum light source and an optical component including a plurality of sections positioned to receive an optical beam produced by the broad spectrum light source. The sections of the optical component are formed to introduce optical path differences into portions of the optical beam that impinge on the optical component such that each section introduces a delay into a corresponding portion of the optical beam. The introduced delays cause each portion of the optical beam to lack coherence with other portions of the optical beam. A direct detection receiver detects the intensity of the aggregate beams and produces a signal with improved signal-to-noise ratio. The disclosed technology can be used with modulated optical beams such as intensity modulated beams.

    Abstract: A quasi-optical coupling system launches and extracts surface wave communication transmissions from a wire. At millimeter-wave frequencies, where the wavelength is small compared to the macroscopic size of the equipment, the millimeter-wave transmissions can be transported from one place to another and diverted via lenses and reflectors, much like visible light. Transmitters and receivers can be positioned near telephone and power lines and reflectors placed on or near the cables can reflect transmissions onto or off of the cables. The lenses on the transmitters are focused, and the reflectors positioned such that the reflected transmissions are guided waves on the surface of the cables. The reflectors can be polarization sensitive, where one or more of a set of guided wave modes can be reflected off the wire based on the polarization of the guided wave modes and polarization and orientation of the reflector.
