Abstract

We theoretically investigate phase modulators based on the quantum-confined Stark effect. Our analysis incorporates electronic wavefunctions derived from the transfer matrix method in the effective mass approximation and is therefore more accurate than variational procedures. To describe exciton broadening we include phonon scattering and the electric-field induced tunneling out of the quantum well. Our results model correctly most characteristics of the measured refractive index change.
