Abstract

A new type of stimulated Brillouin scattering (SBS) suppression fiber has been developed whose dopant concentration and core radius are nonuniform along its length. The chromatic dispersion distribution is kept uniform along its length by varying the core radius in accordance with the /spl Delta/ value to enhance four-wave mixing (FWM) intentionally. The output power of the FWM signal with this fiber was about 15 dB higher than that with a conventional disperion-shifted fiber when the input power was 15 dBm, which is just above the SBS threshold power.
