BeamLab is an award-winning set of simulation tools for beam propagation through optical devices and waveguides in your familiar MATLAB® environment — no hassle with learning a new proprietary language or CAD tools, and utmost flexibility in post-processing and editing of any output data and graphs. BeamLab consists of two toolboxes, the Beam Propagation Toolbox and Mode Solver Toolbox, for analyzing beam propagation in waveguides as well as free space, and computing eigenmodes of waveguides with arbitrary cross-sections. Solving complex optical problems has never been easier!

Simple Coding

The following few lines of code produce a video that shows the light vortex in a multimode fiber generated by a Gaussian beam at oblique incidence and slightly offset from the fiber axis.

%% Input parameters for BPM simulation
gridPoints = [200 200];
gridSize = [100 100];
lambda = 1.55;
indexFunction{1} = @(b) homogeneous(b,200,1);
indexFunction{2} = @(b) singlecore(b,4800,[50 50],1.46,1.45);
inputField = @(b) gaussinput(b,[15 15],...
    'Shift',[15 0 200],'Angle',[5 90]);

%% Create beamProblem
beamProblem = beamset(gridPoints,gridSize,lambda,...
    indexFunction,inputField,...
    'Video',true,'IndexContour','all');

%% Start BPM calculation
bpmData = bpmsolver(beamProblem);

What our beamlab users say

Elad Oved
After testing 13(!) programs, I found BeamLab the simplest for simulating graded index waveguides in complex geometries. Working within the MATLAB environment makes the design and analysis using BeamLab easy and flexible.
