BPM simulator for active and passive semiconductor IOC

We have added to our very general, user friendly simulator for integrated optical circuits the capability to analyze structures made with semiconductor materials whose characteristics are controlled with current injection. The simulator is interfaced with the optical layout generator SIGRAPHTM-Optik (by Siemens-Nixdorf) and it is based on a finite difference BPM with transparent boundary conditions. Some examples of applications are presented; they show the agreement with the results reported in the literature and the potentiality of the simulator.
