# SimMoLFil
A **Mode-Locked Fiber Laser (MoLFil)** simulator.
## General info
This project simulates pulses generation and evolution in mode-locke fiber lasers.
The pulse evolution in fiber is calcuated by solving GNLSE using Interaction Picture Method Algorithm [[1](https://ieeexplore.ieee.org/abstract/document/6153336)].
The [original codes](https://github.com/SeveNOlogy7/SimMoLFil/tree/e5cd7787960a503ebab0ab7e6fc6a859b3413667) of this project were written for this paper [[2](https://www.osapublishing.org/oe/abstract.cfm?uri=oe-25-4-4414)], which contains only a minimum amount of the whole codes used.
The project is currently under development.
## Technologies
The project is created with:
* MATLAB version: 2018b
## Examples
mainP1.m: run a simulation and produce results of Point 1 of Figure 2 in [[2](https://www.osapublishing.org/oe/abstract.cfm?uri=oe-25-4-4414)].
## Works in progress
A simple data flow graph (DFG) presentation of Mode-Locked Fiber Laser Models to seperate
layout and connection of optical components from their implementation.
A DFG presentation can be built into some evaluatable object by a Builder.
Imaging you can simply write somthing like
```MATLAB
model = defind some model use DFG
evaluaion = model.build(Some Builder)
evaluaion(Some simulation settings)
```
In this way, it is easy to evaluate a same model with
* different simulation settings (more points, fine step, etc.),
* different algorithms to simulate some specific kind of optical components (better gain model, multimode pulse simulation, etc.),
* and even tools written in other language.
All these can be done by adding a new Builder class to generate the evaluatable.
Also, it turns out to be clear that, the idea of DFG presentation is not only suitable for Mode-locked fiber laser models, but also for Cascaded Fiber Supercontinuum Generation models.
### Examples of current DFG design
Following are codes that generate a Cascaded Fiber Supercontinuum model.
```MATLAB
% Define a fiber component
fiber = component.Fiber();
% Create some "Node"s that performs Fiber operation
% SMF stands for single mode fiber
SMF1 = simulation.Fiber("SMF1", fiber);
SMF2 = simulation.Fiber("SMF2", fiber);
SMF3 = simulation.Fiber("SMF3", fiber);
% Create a input Node
In = simulation.Input("In");
% Now simply put the Nodes together
% Think it like:
% Out = In -> SMF1 -> SMF2 -> SMF3
% It is injecting a input (like a powerful laser pulse) through three cascaded fiber sections
% No "->" operator in Matlab, so it end up like this
Out = In + SMF1 + SMF2 + SMF3;
% Generate some human-readable statement presentation of the model
statements = Out.statements()
```
The statements will contain a multiline string:
```MATLAB
t0 = In.Input()
t1 = SMF1.Fiber[fiber=component.Fiber](t0)
t2 = SMF2.Fiber[fiber=component.Fiber](t1)
t3 = SMF3.Fiber[fiber=component.Fiber](t2)
```
These staments show what any builders of the DFG model should implement to make the DFG an evaluable.
### Codes Arrangement
* **simulation package** contains codes that help reuse a few MATLAB syntax to present a MoLFil Model in DFG
and simply build the MoLFil Model to
* Human readable statements
* Evaluation object, given a specific Builder implementation
* **component package** contains optical components packed in classes.
And some helper methods to calculate parameters for those components.
