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 solvers, the BPM Solver and the Mode Solver, for analyzing beam propagation in waveguides as well as free space, and computing eigenmodes of waveguides with arbitrary cross-sections. BPM Solver implements a beam propagation solver based on the Finite Difference Beam Propagation Method (FD-BPM), and Mode Solver implements a waveguide eigenmode solver based on the Finite Difference Method (FDM). Solving complex optical problems has never been easier!

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);
