A spectral-inversion technique with no wavelength shift is presented that utilizes a novel four-wave mixing (FWM) scheme named the optical parametric loop mirror. This scheme eliminates both the input signal wave and the nondegenerate pump waves from the FWM wave generated at the signal wavelength. The compensation of waveform distortion caused by fiber chromatic dispersion is successfully demonstrated by the proposed method.
