BeamLab is an award-winning set of simulation tools for beam propagation through optical devices and waveguides in your familiar MATLAB® environment. Examples encompass a large variety of propagation scenarios for both bulk and waveguide optics including lenses, gratings, apertures, couplers, splitters, multiplexers, and modulators.

New release v1.1: Now with material database and parallel computing (September 2017)

Unlimited Plotting Options

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.
