    Abstract: Method and system for providing autonomous real time updates of a network topology. The method is based on a physical layer point-to-point protocol residing in each network element (210, 220). Either responsive to a request from a network management system (230) or responsive to network trigger event a network initiates a request to its neighboring network elements. The neighboring network elements respond to the request by identifying themselves via an electronic serial number and the port by which they are connected to the requesting network element. The requesting network element then forwards the response to the request to a network management system (230). The network management system (230) then uses the responses to construct a network topology.

    Abstract: A system and method for transporting encrypted data having a transmitter and a receiver is provided. The transmitter generates a sequence of optical pulses, which are copied and output as identical channels. The identical channels are modulated by a plurality of modulators using data to generate a modulated data signal. Respective spectral phase encoders coupled to each of the plurality of data modulators encode respective modulated data signals using a plurality of mutually orthogonal phase codes that are individually associated with the respective spectral phase encoder. These encoded data signals are combined and code-scrambling by a spectral phase scrambler t using a scramble code as an encryption key to generate an encrypted signal. A receiver reverses the encryption to extract the data.

    Abstract: Systems and methods for improved photonically-assisted RF filtering. Presently, processing of wide-band RF signals involves the use of multiple specialized equipment to isolate a region of interest from the spectrum. The present invention discloses the use of a modulation system to upconvert the RF signal onto the sideband of a light source such as a laser, an optical filter sub-system comprising a plurality of filtering units that function as combinations of HR and FTR filters, and a resonant channelizing filter for noise reduction and rejection of undesired channels, and means for control and agility of a piecewise coherent optical filter. The resulting filtered RF signal may then be downconverted to the electrical domain for further signal processing.
