pyofss 0.8

Optical fibre system simulator

Pyofss allows construction of an optical fibre system from separate modules. A typical system consists of a Gaussian pulse generator module and an optical fibre module. The field generated is propagated through the fibre by numerical integration of an appropriate Schrödinger-type equation. Simulated effects include that of dispersion (second, third, and higher order), attenuation, self-phase modulation, self-steepening, and Raman scattering. Resulting field profiles (including multiple traces for the fibre module) may be visualised using a range of plot types. These include standard x-y plots, top-down “map” plots, three-dimensional “waterfall” plots, and animation videos.

Installation

Warning

Some of the following commands may require superuser privileges. Use:

$ sudo command

or:

$ su root

then run the commands.

Always be cautious when running with enhanced privileges!

Pyofss is available on Pypi and may be retrieved using the pip program:

$ aptitude install pip
$ pip install pyofss

Then import pyofss within scripts or in an interactive session:

>>> from pyofss import *

Note

If the required dependencies are not satisfied when installing pyofss, then manually install using either:

$ aptitude install python-numpy python-scipy python-matplotlib

or:

$ pip install numpy scipy matplotlib

The recommended versions are listed in the “requirements.txt” file within the pyofss package. Using this file, it is possible to automatically install all dependencies:

$ pip install -r requirements.txt
