Abstract

The invention discloses a double-conjugation pumping modulating signal all-optical regeneration device based on an optical frequency comb. The all-optical regeneration device comprises a pumping laser device, the optical frequency comb, a photodecomposition multiplexer, a first coupler, erbium-doped optical fibers, a second coupler, a first section of HNLF, a wavelength selective switch, a second section of HNLF and a light bandpass filter. The device can be used for phase position regeneration of various degraded QPSL signals (including DQPSK) in a high-speed optical fiber communication network, so that influence on performance of an optical communication system by phase noise is reduced, the all-optical relay transmission distance is improved, and the error rate of a receiver is reduced. The invention further discloses a double-conjugation pumping modulating signal all-optical regeneration method based on the optical frequency comb. The double-conjugation pumping modulating signal all-optical regeneration device has the advantages of being concise in structure, stable in performance, easy to operate, remarkable in regeneration effect and the like.

Description

technical field [0001] The invention relates to an all-optical phase regeneration technology of a phase modulation signal in the field of high-speed optical fiber communication, in particular to an all-optical phase regeneration device and method for a double-conjugate pump phase modulation signal based on an optical frequency comb. Background technique [0002] With the rapid development of my country's economic entities and the continuous improvement of network infrastructure, my country's Internet demand for bandwidth will maintain a long-term high-speed growth. In order to effectively cope with the bandwidth capacity crisis caused by the explosive growth of various applications, various communication technologies have been proposed to break through the bottleneck of traditional optical fiber transmission capacity. Polarization multiplexing, time-division multiplexing, wavelength-division multiplexing, and recently emerging space-division multiplexing have enabled the sin...
