Latest Patents
One of his latest patents is titled "Method and system for selective optical payload cancellation." This invention provides a method and system for selectively canceling a specified frequency band in the payload of an optical communication system. The selected frequency band is utilized for launching pilot tones for power measurement and identification. The method controls the intensity of the optical payload signal through an intensity modulator included in the optical communication system. The frequency band in the payload to be canceled is removed, while the other frequency components of the payload are passed without attenuation. An embodiment that uses a feed-forward unit, a feedback unit, and a control unit for generating a cancellation signal for the intensity modulator is described. An advantage of this method is that it effectively removes a continuum of payload tones in the specified frequency band to be canceled.
Another notable patent is "Method and system for precision cross-talk cancellation in optical amplifiers." This invention provides improved methods and systems for precise and selective cross-talk cancellation and pilot tones deletion in optical amplifiers. The method for cancellation of cross-talk among multiple channels occurring in a traditional optical amplifier involves detecting tones at both the input and output of a Smart Optical Amplifier, which includes a traditional optical amplifier and a Cross-talk Cancellation Unit. The detected tones are compared, and destructive tones are generated with specific amplitudes and phases to cancel cross-talk. This process eradicates cross-talk at the output of the Smart Optical Amplifier by applying the destructive tones in the Cross-talk Cancellation Unit. Eight different embodiments correspond to various combinations of traditional optical amplifier types and the technology used in processing and control of signals.
