Abstract
We have demonstrated a 1.5-μm, 333-km, 10-Gb/s transmission system in conventional 1.3-μm zero-dispersion-wavelength single-mode fiber, using mid-span spectral inversion In a multi-mode semiconductor laser. The inverted spectrum was generated via cavity-enhanced highly-nondegenerate four-wave mixing, for which the resonant gain in the injection-locked V-groove laser yields higher conversion efficiencies relative to those of travelling-wave amplifiers. The bit-rate×distance product of 3330 Gb-km/s is more than an order of magnitude better than the best previous result employing a semiconductor conjugator.
