    Abstract: An optical receiver component, wherein the receiver component comprises a first type of partial-voltage source with a first absorption edge and a second type of partial-voltage source with a second absorption edge, and the first absorption edge lies at a higher energy than the second absorption edge. Each partial-voltage source produces a partial voltage, provided a photon flux at a specific wavelength strikes the partial-voltage source, and the two partial-voltage sources are connected in series. A first number of series-connected sub-partial-voltage sources of the first type and a second number of series-connected sub-partial-voltage sources of the second type are provided. The first number and/or the second number are greater than one, and the respective deviation of the source voltages of the sub-partial-voltage sources among themselves is less than 20% in both types.

  • Patent number: 10054691
    Abstract: A solid-state radiation detector includes a pattern of conductive metal on a zinc oxide substrate. The pattern provides an arrangement of interdigitated electrode fingers. The wide band gap substrate is sensitive to UV light, which can cause a conductivity change in the substrate. The electrode fingers are configured to sense a difference in substrate conductivity resulting from UV light. The detector has a fast response time, which enables it to detect Cherenkov light. The compact detector provides savings on size, weight, and required power. Thus, the solid-state detector can be used to replace photomultiplier tubes in Cherenkov detectors. The features of the novel detector allow for an improved system to detect and monitor UV radiation, especially during deep space missions.

  • Patent number: 10050699
    Abstract: Described herein is a space based subsystem of a satellite, and methods for use therewith, for receiving an optical ISL beam from another satellite, and in dependence therein, producing a further optical ISL beam for transmission to a further satellite. Additionally, the subsystem can also produce RF service downlink beams for transmission to service terminals. The subsystem can include, inter alia, receiver optics, optical amplifiers, a WDM demultiplexer, beam splitters, a WDM multiplexer, and transmitter optics. In certain embodiments, because RF frequencies of a wavelength division multiplexed optical signal produced by the WDM multiplexer are within a same specified RF frequency range within which the satellite and the further satellite are configured to transmit RF service downlink beams, there is an elimination of any need for the satellite and further satellite to perform any frequency conversions when producing the RF service downlink beams in dependence on the optical ISL beams.

  • Publication number: 20180227271
    Abstract: First and second applications are executed in a red domain, and a third application is executed in a black domain, with a lower security level, and via which a ciphered communication tunnel passes between the first and second applications. The first application transmits to the second application a nominal sequence of packets ordered according to their respective sizes; said nominal sequence is intercepted by the third application which, when it wishes to transmit information to the red domain, modifies said nominal sequence by deleting at least one packet, each deleted packet being dependent on said information; on reception of a sequence of packets supposed to be the nominal sequence of packets, the second application checks whether at least one packet has been deleted; and, if such is the case, the second application retrieves said information from the size of each packet thus deleted.
