摘要： In some embodiments, an optical communication system may include an optical source, a modulator, and a photoreceiver. The optical source may be configured to generate a beam comprising a series of light pulses each having a duration of less than 100 picoseconds. The photoreceiver may have a detection window duration of less than 1 nanosecond. When a first pulse travels through a variably refractive medium, photons in the first pulse may be refracted to travel along different ray paths to arrive at the photoreceiver according to a temporal distribution curve. A full width at half maximum (FWHM) value of the temporal distribution curve may be at least three times as large as a coherence time value of the first pulse, and the detection window of the photoreceiver may be at least six times as large as the FWHM value of the temporal distribution curve.

摘要： Systems and methods are described for transmitting information optically. For instance, a system may include an optical source configured to generate a beam of light. The system may include at least one modulator configured to encode data on the beam of light to produce an encoded beam of light/encoded plurality of pulses. The system may include a spectrally-equalizing amplifier configured to receive the encoded beam of light/encoded plurality of pulses from the at least one modulator and both amplify and filter the encoded beam of light/encoded plurality of pulses to produce a filtered beam of light/filtered plurality of pulses, thereby spectrally equalizing a gain applied to the encoded beam of light. In some cases, the system may slice the beam of slight, to ensure a detector has impulsive detection. In some cases, the system may include a temperature controller to shift a distribution curve of wavelengths of the optical source.

摘要： System, method, and instrumentalities are described herein for transmitting information optically. The optical source may be configured to generate a beam. The beam may include a series of light pulses. The beam of light may be modulated. A modulator may be configured to modulate the series of light pulses in response to a data transmission signal, thereby encoding transmission data into the series of light pulses. The modulated beam of light may be received and both amplified and filtered. The filtered beam of light may be transmitted from to a detector having a photoreceiver. The photoreceiver may be configured to extract the transmission data from the filtered beam of light.

摘要： Systems and methods are described for transmitting information optically in free space. For instance, a system may include an optical signal generator to generate an amplified beam of light. A telescope transmits the amplified beam through the medium and receives an inbound beam of light. A detector system may include one or more (or multiple) detectors and a routing system that transmits the inbound beam to a selected set of detectors. In some cases, the system can determine a re-configuration condition based on control parameters and perform a system re-configuration to direct the inbound beam to a different set of detectors. In some cases, the system includes a remote fiber head or wavelength division multiplexing.
