semiconductor laser simulator, programs GLAD and DILAS?

[Richard Gnall]

Does anyone know of a good semiconductor laser simulator?
Does anyone have any experience with or heard of programs GLAD and
DILAS?

Thanks,

My company, Virtual Photonics, produces a program called OPALS
(Optoelectronic, Photonic and Advanced Laser Simulator) that can
simulate not only semiconductor lasers, but complete photonic systems.

The laser models within OPALS will handle small and large signal
modulation, single and multi-wavelength devices, chirping of laser
modes, reflections from external sources back into a laser,
mode-locking, external locking of a laser mode to a single frequency,
four-wave mixing in lasers and Semiconductor Optical Amplifiers, FP and
DFB lasers, with arbitrary phase shifts (including facet phases),
multi-contact devices etc. You can apply a variety of modulation
formats to the laser, or import a drive waveform from another package.
You can view the outputs in the time and frequency domain,
simultaneously if you wish, so that you can see the evolution of a
pulse, and it's spectrum, simultaneously, as the simulation runs. All
models are numerically efficient, and OPALS runs on Mac, PC and Sun
platforms.

In addition, the laser simulator is only a small part of the OPALS
package. You can feed the output from the laser into a photonic system,
down a fibre, into a photodiode, and see the system response. OPALS
includes compatible models for a wide range of photonic components and
instrumentation. Finally, OPALS has an easy to use, graphical user
interface, and the models within OPALS are validated by a large number
of publications in the literature.

If you are interested in OPALS, please see our web page
