Elimination of wavelength shifts in spectral inversion in optical networks

摘要

PROBLEM TO BE SOLVED: To provide a method and system for erasure of wavelength shift in spectrum inversion in an optical network.SOLUTION: The method includes receiving an input optical signal, and generating a combined optical signal by combining the input optical signal having an input wavelength with a first pump signal having a first wavelength by Bragg scattering. The method further includes converting the combined optical signal into an output optical signal by phase conjugation using a second pump signal having a second wavelength. The output optical signal has the same wavelength as the input optical signal.SELECTED DRAWING: Figure 3
