COMSOL-based Ostendo’s Optoelectronic Device Modeling Software (ODMS) has been updated to include effects of non-equilibrium QW populations in semiconductor light-emitting and laser diodes.

III-nitride light emitters with different levels of polarity have been compared as an illustrative example of ODMS performance. Modeling proved that high intra-QW recombination rates in III-nitride light emitters make the QW populations strongly non-equilibrium and vulnerable to inhomogeneous injection in multiple-QW devices.

QW populations are further affected by disparate electron and hole transport across the active region.
