Laser simulation is implemented as part of the Atlas device simulation framework Atlas provides framework integration Blaze provides III-V and II-VI device simulation Laser provides optical emission capabilities for edge-emitting lasers VCSEL p. III-V Device Simulation maturity has conventionally lagged behind silicon leading to many immature standalone tools with a low user base Users must ensure that the simulator they evaluate has all the necessary components Blaze shares many common components of the Atlas framework with the mature and heavily used silicon simulator, S-Pisces Blaze i. Blaze uses currently available material and model coefficients taken from published data and university partners For some materials often very little literature information is available, especially composition dependent parameters for tenrary compoundsSome parameters (eg. Process simulationInternal Atlas syntax limited to rectangular structuresStandalone device editor (DevEdit) GUI to define structure, doping and mesh batch mode for experimentation abrupt and graded mole fraction definition non-rectangular regions supported Structure Creation Using DevEditLaser works within the framework of Atlas and Blaze. Blaze provide electrical simulation of heterostructure devices and material models for common III-V and II-VI semiconductors Self-consistently solves the Helmholtz equation to calculate optical field and photon densities Accounts for carrier recombination.
