Abstract
The barrier reservoir and QW electron transfer (BRAQWET) concept was introduced by Wegener et al. in 1989.1 In BRAQWETs, electroabsorptive/refractive modulation due to voltage-controlled carrier density effects is utilized. One period of a BRAQWET structure consists of an n-doped reservoir layer, one or more QWs, a p-doped barrier layer and a number of intrinsic layers. These periods can be stacked to increase the interaction between light and matter.
