Abstract
A bias-dependent dual focus Fresnel lens-modulator, based on the quantum co nfined Stark effect in a GaAs/Al0.3Ga0.7As multiquantum well pin diode, is demonstrated. A focused intensity modulation of a factor of 7, primarily du e to the electroabsorption effect, is obtained with a bias change of 12 V.
