ABSTRACT
We formulated a Wigner function-based model for quantum well (QW) lasers. This model has benefits over other models as it is less phenomenological and can be generalized easily to incorporate additional effects. We start with standard non-equilibrium Green's functions and apply the Wigner transformations as well as some key techniques to get a complete system of equations. We include bias potential and electromagnetic interactions. We will also discuss some of the possible generalizations.
