Tapered Laser Utility Product Overview

Simulation Software for Tapered Semiconductor Laser Diodes

The Tapered Laser Utility™[1] provides an efficient and accurate design tool for analyzing and optimizing tapered semiconductor laser diodes. It essentially combines two of RSoft's most powerful and mature simulation tools, BeamPROP and LaserMOD, to provide a full 3D simulation of tapered laser diodes. The quasi-3D electrical, quantum mechanical gain and thermal calculations are performed via LaserMOD, whereas the optical field is propagated via BeamPROP.

[1] The Tapered Laser Utility provides owners of BeamPROP and LaserMOD the functionality described here. All simulation tools are licensed separately.
