Abstract

Electroabsorption modulation is demonstrated in low-temperature-grown InGaAs/InAlAs multiple quantum wells exhibiting 600 fs nonlinear absorption recovery associated with anneal-stable Be-As defects. We show that the absorption recovery time, which depends on the active-defect density, can be controlled by adjusting the Be-doping concentration.
