Rsoft Tutorials 3. Fiber Structures and BeamPROP Simulation Animations

An interesting feature of BeamPROP simulations and other simulators in the Rsoft packages is that the simulation results can be displayed in a running animation. The following simulation is the result of a simulation of an optical fiber. BeamPROP simulates the transverse field in an animation as a function of the z parameter, which is the length of the optical fiber.

To design an optical fiber component with Rsoft CAD, select under 3D structure type, “Fiber” when making a new project.


To build a cylinder that will be the optical fiber, select the cylinder CAD tool (shown below) and use the tool to draw in the axis that the base of the cylinder is found.


Dimensions of the fiber can be specified using the symbol tool discussed previously and by right-clicking the object to assign these values. Note that animations of mode patterns through long waveguides is not only available for cylindrical fibers. Fibers may consist of a variety of shapes. Multiple pathways may be included. Simulations can indicate if a waveguide has potential leaks in it or the interaction of light with a new surface.
