  • CSCML - Optical Cryptography for Cyber Secured and Stealthy Fiber-Optic Communication Transmission
    Lecture Notes in Computer Science, 2018
    Co-Authors: Tomer Yeminy, Eyal Wohlgemuth, Dan Sadot, Zeev Zalevsky
    Abstract:

    We propose a method for stealthy, covert, fiber-Optic Communication. In this method, the power of the transmitted signal is spread and lowered below the noise level both in time as well as in frequency domains which makes the signal “invisible”. The method is also efficient in jamming avoidance.

  • spectral and temporal stealthy fiber Optic Communication using sampling and phase encoding
    Optics Express, 2011
    Co-Authors: Tomer Yeminy, Dan Sadot, Zeev Zalevsky
    Abstract:

    We propose a method for covert fiber-Optic Communication in both frequency and time domains. The power spectral density of the pulse sequence bearing the information is spread in the frequency domain below the noise level by means of sampling. In addition, temporal phase encryption prevents the coherent addition of the various pulses in the frequency domain, further reducing the signal power spectral density. Thus, there is no need to transmit the signal within the bandwidth of a public user in order to spectrally conceal the signal. Temporal spreading of the pulse sequence is achieved by spectral phase encoding, resulting in a stealthy temporal and spectral transmission.

  • Coherent subcarrier fiber-Optic Communication systems with phase-noise cancellation
    IEEE Transactions on Communications, 1994
    Co-Authors: C. Kwong, Paul R. Prucnal, Malvin C. Teich
    Abstract:

    A phase-noise-cancelled coherent subcarrier fiber- Optic Communication system that uses integrated-Optic Mach- Zehnder waveguide modulators for frequency-pair encoding is introduced. Optical double-sideband suppressed-carrier signals with the same random phase noise and information encoded in the frequency separation of the two sidebands are generated by properly biasing the modulator. Phase noise is eliminated at the receiver by a nodhear operation on the two sidebands. System performance analysis with numerid examples, taking into ac- count the modulation index and laser normalized linewidth, is presented.
