We demonstrate a surface-normal coupled-quantum-well InGaAs-InAlAs electroabsorption
modulator that provides optical modulation with a contrast ratio in excess of 1.5 at only 6 V …

A numerical method for the analysis of the absorption spectrum and the refractive index
change due to an external electric field in quantum-well structures is presented. The finite …

Excitons in a double-quantum-well structure, consisting of two wells separated by a thin
barrier, are studied. Binding energies and oscillator strengths of the exciton ground state are …

We have studied the modulation properties of a vertical cavity surface-emitting laser
(VCSEL) coupled to an electrooptical modulator. It is shown that, if the modulator is placed in …

The authors model the room temperature electroabsorption of coupled double quantum
wells using a transfer matrix technique to calculate carrier wavefunctions and their overlaps …

We have calculated by a variational procedure the excitonic states in symmetric coupled
quantum well structures of GaAs/AlGaAs in the presence of an external electric field …
