# 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. ### Todos - [x] DFG generation - [x] DFG build process - [x] A pure MATLAB Builder implementation using existing codes in SimMLFL - [x] DFG Evaluation Class - [x] flow control operations - [ ] Fill component package with concrete classes - [x] components need for F8L - [ ] more components - [ ] Docs - [ ] Examples
