Optical soliton impulse compact characteristic calculating program

Abstract

The invention relates to an optical soliton impulse compact characteristic calculating program, belonging to the technical field of fiber communication. The calculating program can calculate the compact characteristic of cross polarization optical soliton impulse under various conditions by regulating different parameters (such as amplitude of input impulse, impulse time domain width, initial time domain interval, initial chirp C, size of time domain window used in calculating, sampling points, different fiber parameters and transmission distances), and solves the problem that the compact characteristic of the optical soliton is difficult to analyze and study in a process of designing and optimizing an optical logic device and a polarization multiplexing system. The calculating program is easy and understandable, has convenient operation, powerful functions, high calculating speed, convenient drawing and strong practicality, can modify related parameters according to actual condition to carry out related study under various conditions, provides powerful support for optimization of fiber communication systems and related key devices (such as optical soliton switches and other optical logic devices) and further study in the field, and pushes fast development of the subject.

Description

Technical field [0001] The invention relates to a program for calculating collision characteristics of optical soliton pulses, and belongs to the technical field of optical fiber communication. Background technique [0002] Soliton collisions in birefringent fibers are of scientific importance, and have important practical value in optical logic devices and polarization multiplexing systems, which have aroused extensive interest of scientific and technological workers. The initial interval of two polarized solitons can be flexibly set according to practical applications. In an optical logic device, one polarization state soliton is used as a data signal, and the other polarization state soliton is used as a control signal, and the initial time interval can be different; at the input end, by adjusting the time interval, chirp, etc. To control whether the two solitons are in the bound state, so that they produce different time delays; at the output end, the corresponding dela...
