Abstract

The embodiment of the invention provides an all-optical shaper and a parameter determination method and device of the all-optical shaper. The shaper comprises an MZI shaping module, a first directional coupler and a second directional coupler, wherein the MZI shaping module comprises an upper arm and a lower arm arranged in parallel with the upper arm; the output end of the first directional coupler is connected with the input end of the MZI shaping module, and the first directional coupler is used for decomposing an input optical signal into two paths of optical signals; one of the two paths of optical signals is subjected to nonlinear phase shift through the upper arm, and the other one of the two paths of optical signals is subjected to linear phase shift through the lower arm; the input end of the second directional coupler is connected with the upper arm and the lower arm of the MZI shaping module, and the second directional coupler is used for coupling the two paths of optical signals output by the upper arm and the lower arm to obtain the shaped optical signals.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an all-optical shaper and a method and device for determining parameters of the all-optical shaper. Background technique [0002] In the optical fiber communication system, the optical signal is easily affected by factors such as fiber dispersion, ASE noise accumulation of the optical amplifier, and interaction between channels during the transmission process, which leads to the degradation of the optical signal and ultimately limits the transmission rate of the system and the network. In order to ensure the reliable transmission of information in the network, it is necessary to regenerate the degraded signal in time. [0003] In related technologies, there are certain limitations in the selection of the shaper structure and the optimization of parameters, and the signal shaped by the shaper is a PAM signal with equal power intervals, which cannot meet the sha...
