Cancellation of spectral spread by pump frequency modulation in optical fiber wavelength converter

摘要

We propose a novel highly-efficient wavelength conversion technique based on the four-wave mixing in the optical fiber, which can suppress not only the stimulated Brillouin scattering but also the spread of the converted spectrum. We proposed and demonstrated a novel highly efficient wavelength conversion technique without spectral spread of the converted signal, in which frequency of pump light and phase of signal light are modulated synchronously. The experimental setup proved our scheme to be effective for highly efficient wavelength conversion without spectral spread.
