Abstract

We developed a model to calculate the electrorefraction due to the Quantum Confined Stark Effect in strained cylindrical QDs. We followed a numerical matrix diagonalization method using an expansion in plane-wave states. The correct polarization dependence is obtained by using the 4X4 Luttinger-Kohn Hamiltonian for the valence band. The exciton wavefunction is also calculated using a diagonalization approach. We will present the absorption spectra as a function of applied electric field and dot dimensions and discuss the implications for the electrorefraction.
