Abstract(in English) An all optical wavelength converter is one of the key devices for high-capacity and flexible optical wavelength division multiplexing (WDM) networks. In particular, wavelength conversion using four-wave mixing (FWM) in optical fibers is attractive because of its broadband characteristics. In order to enhance the conversion efficiency, it is the most effective to increase the pump power. However, the maximum pump power is limited by the stimulated Brillouin scattering (SBS) in optical fibers. It is possible to suppress the SBS by the spread spectrum (SS) scheme, but this scheme has a disadvantage that the spectrum of the converted light is also spread, and as the result degraded by the chromatic dispersion in optical fibers. In this paper, we propose and demonstrate a high-efficiency wavelength conversion technique in which both pump and signal lights are modulated synchronously.
