Abstract

All-optical wavelength conversion has been achieved to generate a multichannel return-to-zero optical source for wavelength-division-multiplexed (WDM) systems by using a nonlinear optical loop mirror consisting of a common dispersion-shifted fiber. After WDM transmission over 40-km SMF, the WDM signals are successfully regenerated by a novel regenerator including reshaping and reamplification based on a dispersion-imbalanced loop mirror consisting of an SMF and a highly nonlinear dispersion-shifted fiber.
