A WDM SYSTEM THAT USES NONLINEAR TEMPORAL GRATINGS AS A NEW OPTICAL SOLITARY WAVE

摘要

A method of generating a signal pulse in an optical fiber characterized bydispersion and a refraction index that has a nonlinear regime of operation,the method including generating a sequence of coherent optical pulses (50)each of which has an associated energy; and introducing the sequence of pulsesinto the optical fiber, wherein the pulses in the sequence of pulses aresufficiently close in spacing so that after traveling a predetermined lengthdown the optical fiber, the pulses of the sequence of pulses overlap andinterfere to form an interference pattern, and wherein the associated energyof at least one of the pulses of the sequence of pulses is within thenonlinear regime of the optical fiber.
