Research Abstract

We have theoretically studied the generation of squeezed photons from a quantum well embedded in a microcavity. As a result, we have found that higher squeezed states can be generated from the coupled states than from a polariton-polariton scattering. In addition, I have developed a new and efficient calculation method of two-exciton states including biexciton in a 1D, 2D, and 3D tight-binding models. This method dramatically improves a computation time and memory size.
