Abstract

The nonlinear (third-order) optical gain for quantum-dot structures is derived where the density matrix theory is defined by the inhomogeneous density matrix elements. Thus, the nonlinear gain becomes completely inhomogeneous. The total gain obtained under complete inhomogeneous density matrix is shown to be asymmetric. This is not included earlier.
