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 by dispersion 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 puls es into the optical fiber, wherein the pulses in the sequence of pulses are sufficiently close in spacing so that after traveling a predetermined length down the optical fiber, the pulses of the sequence of pulses overlap and interfere to form an interference pattern, and wherein the associated energy of at least one of the pulses of the sequence of pulses is within the nonlinear regime of the optical fiber.
