摘要： A method for wireless data transmission between a first communication device and a second communication device, wherein the first communication device acts as a data source and the second communication device acts as a data sink, includes: splitting, by the data source, data to be transmitted from the data source to the data sink into a carrier signal for a radio channel and an optical carrier signal by modulating the carrier signals; transmitting the data via a hybrid transmission path from the data source to the data sink by simultaneously transmitting some of the data via the radio channel and some of the data via a wireless optical direct channel; and merging, by the data sink, via a demodulation process, the data transmitted via the radio channel and the data transmitted via the wireless optical direct channel.

摘要： The present invention relates to an optical communication system and an optical transmission device. By changing the ratio between the first segment and the segment or/and the amplitude of the second segment, the digital signal is modulated and transmitted in the form of an optical signal. Then a solar panel, which is used as the receiver for the optical signal, can receive the optical signal and give directly the one or more digital signal without demodulation. Thereby, the costs of using a solar panel as the optical receiver may be reduced and the transmission rate may be enhanced.

摘要： A free space optical receiver comprising a photodetector and a fiber bundle. The fiber bundle comprises a plurality of optical fibers splayed apart at one of their ends to receive free space optical energy from multiple directions. The splayed apart ends of the plurality of optical fibers may create a hemispherical shape. Each of the plurality of optical fibers has an acceptance cone for which it couples optical energy into the splayed end of the optical fiber. The acceptance cones of the splayed ends of the plurality of optical fibers may overlap to form an omnidirectional acceptance zone. The other, non-splayed ends of the plurality of optical fibers are communicatively coupled to the photodetector, which is positioned to receive the free space optical energy from the non-splayed ends of the plurality of optical fibers. An optical communication system including the free space optical receiver is also described.

摘要： A system and method are disclosed for information assurance for networked systems. The system and method involve a quantum key distribution (QKD) source, a gimbaling device, a receiver, and a sender. The QKD source is mounted on the gimbaling device, and the QKD source propagates energy into an oversized spot beam. The receiver and the sender are within optical communication of each other. The gimbaling device performs pointing acquisition tracking only as necessary to keep the receiver located within the oversized spot beam. When the receiver is located within the oversized spot beam, the QKD source performs a QKD function. In one or more embodiments, the gimbaling device is mounted on a mobile platform. In some embodiments, the mobile platform is mounted on an unmanned aerial vehicle (UAV). In other embodiments, the mobile platform is mounted on a small ground vehicle.

摘要： Enhancements in optical beam propagation performance can be realized through the utilization of ultra-short pulse laser (USPL) sources for laser transmit platforms, which are can be used throughout the telecommunication network infrastructure fabric. One or more of the described and illustrated features of USPL free space-optical (USPL-FSO) laser communications can be used in improving optical propagation through the atmosphere, for example by mitigating optical attenuation and scintillation effects, thereby enhancing effective system availability as well as link budget considerations, as evidenced through experimental studies and theoretical calculations between USPL and fog related atmospheric events.
