Use this software to create a waveguide structure, define an input beam, specify a waveguide length, then use one mouse click to propagate the beam to output. Structures include: photonic crystal fibers, step-index fibers, multi-core fibers, leaky-channel fibers, and more. Find the fundamental propagation mode in seconds or less. Then find the higher-order modes in minutes. Save all projects and reload them for continued study. Export data generated by this code to other software in ASCII format, or save images in BPM format for publication. Save video frames for creating exciting videos of laser beams propagating through waveguides. This code uses a new mathematical technique for solving the time-independent, scalar Helmholtz wave equation allowing the computations to be accomplished much more quickly than with other techniques. Engineering or physics students may use this software to learn more about optical waveguides. Technologists can use this software to design optical waveguides or design fiber lasers.
