2012-02-04 • Server migration

We currently plan an extensive migration of our server infrastructure. In effect, the domains "lenge.de" and "photoss.de" might be not fully functional (or even completely inaccessible) for some time. Of course we aim to have it up and running again as soon as possible, but we cannot guarantee a certain date.

We will not start the process before Saturday (2012-02-11). If you plan any downloads or want contact us by email, you might want to do so until Friday (2012-02-10).

2012-01-16 • PHOTOSS 5.11 released

Besides numerous improvements and the usual bunch of bugfixes, the new version includes:

New: Support for Microsoft® Windows® 7 Service Pack 1, MATLAB® 7.11 (R2010b), and MATLAB® 7.12 (R2011a)
New: Automatic GPU selection for accelerated fiber simulation (if more than one is available) when PHOTOSS is run from the command line
New: Separate user defined A_eff parameter per Raman pump
New: Ability to import a power distribution along a fiber (instead of an attenuation coefficient)
New: Option to save a signal when right-clicking a link
New: Option to open an oscilloscope (amplitude, power, phase, chirp) or a spectrum analyzer (frequency or wavelength, linear or logarithmic) when right-clicking a link
New: In combined simulations, the pattern modifier component may now update the parametric signal with more precise values from the sampled signal (useful for single-channel transmission)

Customers with a valid update subscription will automatically receive the new version within a few days. All other customers are invited to contact us for an according update.
