  • Publication number: 20230319447
    Abstract: A control signal may be modulated on an optical wave. A transmitter may transmit the control signal to a switch/processor location. At the remote node, the control signal is received and converted from an optical signal to an electrical signal to drive the switch/processor. To provide electrical power at the switch/processor location, optical power is transmitted from a distance and converted to electrical power using a series of PDs. Monitoring tones may be sent to the remote node and fed back to the transmitter to realize an operation state and detect a bias drift. Accordingly, an OSP function at a remote node is enabled without using any local electrical power supply.

  • Publication number: 20210364702
    Abstract: A system including an optical waveguide having a length extending from an optical interrogator at a first end, a plurality of light-modulating sensor nodes disposed at predetermined locations along the length of the optical waveguide, and (in some embodiments) a plurality of first beam splitters at each of the predetermined locations along the length of the optical waveguide, each of the first beam splitters configured to direct a portion of an optical signal from the optical interrogator to one of the plurality of light-modulating sensor nodes along an optical waveguide path, and return a reflected optical signal to the optical interrogator in an opposite direction along the same optical waveguide path.

  • Patent number: 10649085
    Abstract: A method and apparatus for authenticating a radar return signal include: generating an outgoing radar beam; generating a pair of entangled photons comprising a signal photon and an idler photon; combining the signal photon with the outgoing radar beam to generate a combined beam; sending the combined beam towards a target; receiving a return beam; detecting the signal photon from the return beam by a quantum illumination receiver; and making a joint detection with the idler photon.

  • Patent number: 9110158
    Abstract: A method for range finding of a target including: generating a first photon and a second photon identical to the first photon; transmitting the first photon towards the target and delaying the second photon by a time delay; receiving the first photon reflected from the target and the delayed second photon; interacting the reflected first photon and the delayed second photon to produce HOM interference; detecting photo-statistics at an output of the HOM interference; when the two photons are output at the same output port, repeating the above processes; when the reflected first single photon and the delayed second single photon are output at different output ports, changing the time delay and repeating the above processes; repeating the above processes for a number of times to arrive at a final estimate for a value of the time delay corresponding to the final estimate of the target range.
