SSFM Optical Fiber Solver

File List

• WaveGenerator.py: Generate waveform based on communication parameters and bits to transmit.

• SSFMSolver.py: Simulate the transmission of optical fiber by Split Step Fourier Method.

• Demodulator.py: Demodulate and plot constellation.

• workspace.ipynb: Detailed introduction in Chinese as well as project "playground".

• test.py: A temporary file to test language features for a Python beginner. (Why it's here?)

  Remember to check your directory before git add *.py, please. XD

Function List

• Generate waveform in the form of single-channel, WDM, PDM.

  Signal generation of WDM and PDM is not tested yet!

• Transmission of single-channel or WDM signal.

• Coherent demodulation and constellation plot.

Functions in the Future

• More modulation methods: QPSK, 16QAM, 32QAM, 128QAM.
• More functional interfaces: color map of the whole propagation, animation of constellation rotation, etc.
• Complete mathematical analysis over the Schrödinger Equation and digital simulation.
• Acceleration leveraging NN and other AI tools.

光纤传输的数值仿真计算，基于非线性薛定谔方程形式的脉冲传输方程，使用分步傅里叶法计算。

目前可以求解不考虑偏振效应时的光纤传输，并能对单个频带进行解调。

下一步将完善调制、解调方式，并让这几个类用起来更舒适（或许吧，别抱太大希望）。
