摘要

With the development of the optics communication system and optical signal modulation technology,the amplitude-shift keying (ASK) and phase-shift keying (PSK) are both used in different optical communication sub-networks.In this paper,a novel all-optical modulation format from PSK to ASK based on phase-sensitive amplification is proposed and demonstrated.Using the nonlinear interference of the single-pump phase-sensitive amplification,the signal wavelength can be preserved while the modulation format is conversed.The proposed scheme provides the flexible intermediate node interface transformation in future optical networks.
