Abstract :
In this study we present measurements of the intrinsic properties of three quantum systems: bound and excitonic QWs states, and QDs. We start by measuring the external properties of two saturable absorbers, one with QWs and the other with QDs. By fitting this measured external data, we then calculate the intrinsic properties of each of the three quantum systems and compare their merits as saturable absorbing materials
