Abstract :
Detailed theoretical estimations of the optical properties of InGaAsP QW-EAM´s operating at ~1550 nm were executed. Subsequently, asymmetric double quantum wells are predicted to enhance slope efficiency by more than 350% at a reduced operating bias field of 34 kV/cm compared with ~70 kV/cm for comparable SQW´s.
