A circularly symmetric structure is assumed. The model used for the material gain is both carrier and temperature dependent, with the nonlinear dependency introduced by the use of a phenomenological gain suppression factor. The model is flexible enough to be used for either gain-guided or index-guided structures, whose operation is very much affected by thermal effects, composed of triple GaInNAs quantum wells with Al(Ga)As/GaAs p- and n-type DBR stack.
