Multichannel transmission of intensity- and phase-modulated signals by optical phase conjugation using a quantum-dot semiconductor optical amplifier.
We report the demonstration of optical phase conjugation using a quantum-dot semiconductor optical amplifier. The transmission performance of wavelength-multiplexed 10-Gbit/s intensity- and phase-modulated signals is investigated for different channel alignments. In a 100-km transmission, we have successfully achieved high transmission performance with low power penalties for all the transmitted signals.
