|
Auger module now available. Manual updated to include
description of Auger calculations.
|
|
SimuLase: New demo version available now with some corrections
to the graphics interface.

Release of SimuLase Version 1.1
|
|

|
New tool: New tool calculating the linewidth enhancement
factor incorporated.
|
|
Export Dataset: New feature that allows to export
displayed data into ASCII-files for import into other software like Excel.
|
|
SimuLase manual: updated to explain the new features.
|
|
Confinement factor: corrected an error in the confinement
factor calculation that could have occured if 'Solve Drift Diffusion' was
checked or the structure included extremely thin layers.
|

|
SimuLase manual: Extended Sec. 5.7, "Possible Speed-Ups",
to give some more details for specific examples.
Updated the manual for recent changes in the program.
|
|
Created files: SimuLase now also writes out the
strain into files named "name_TTT_strain.dat". These files are created
in the GainDatabase directory. There is currently no plotting-tool included
in SimuLase for these files.
|
|
GainDatabase time estimate: Changed the algorithm
that estimates the time required to set up a Database.
|
|
Drift diffusion solver: corrected an error due to which
the drift-diffusion problem was only solved in the calculation for the first entry
of the list of carrier densities.
|

Optical mode solver: Now, the optical confinement
factor is no longer calculated from the overlap of the mode with layers
marked as being of type 'Well'. Instead, the confinement factor is calculated
from the overlap of the mode with all layers where the confinement potential bandgap energy
is smaller than the energy corresponding to the operating 'Wavelength' as specified
on the 'Advanced' panel of the 'Design Structure' tool.
The type 'Well' or 'Barrier' is now only used for the determination of the
required subbands.
|
|
Optical mode solver: Increased stability and accuracy
such that it should find confined modes where it previously didn't.
|
|
Optical mode solver: Corrected error in the confinement
factor calculation that appeared for structures with graded composition ('GRINSCH-type' layers).
|
|
Plot windows: Corrected error that occured
when zooming into plots with log-scale axis.
|
Current Calculator tool: We added the
possibility to calculate for radiative losses averaged for TE- and TM-polarization
(Jrad=2/3 Jrad,TE + 1/3 Jrad,TM).
Also, changed the way the material loss or wavelength is re-set after changes in the settings.
|
Gain vs. Current tool: We added the
possibility to calculate for radiative losses averaged for TE- and TM-polarization
(Jrad=2/3 Jrad,TE + 1/3 Jrad,TM).
Also, included Auger losses - if available - in the calculation.
