Research output: Contribution to journalArticlepeer-review


A theoretical model is presented for the current-voltage characteristics of an InGaAs/InAlAs multiquantum-well optical modulator with tunable charge density. The current-voltage characteristics are derived from a drift-diffusion and thermionic emission current model within a selfconsistent Poisson-Schrodinger scheme and show good agreement with experiment. A short-period structure with small leakage current and high breakdown voltage is proposed.
