TODO - The European Community COST 240 Project compares the results of
different laser models obtained for static, dynamic and noise related
characteristics. The devices that have been analysed include AR-coated
lambda/4-shifted DFB lasers with different normalised coupling constant
kappaL, but also DFB lasers with cleaved facets. From the numerical
results obtained so far, it seems that an excellent agreement can be
obtained in most cases. Also, those cases where a disagreement between
models is found show where more crude approximations fail, and so can
give an indication of the validity range of several approximations. A
few such cases are reported in the text. Eleven laser models are
compared. All of these models make use of a similar approach (allowing a
nonuniform carrier density) for the static analysis, but the details of
the calculations differ significantly for what concerns the dynamic and
noise related characteristics.
