Abstract
A normally-on high-performance asymmetric Fabry–Perot modulator using the quantum confined Stark effect in GaAs quantum wells confined by short period AlAs–GaAs superlattices is reported. The modulator is the first of this type to exhibit simultaneously low insertion loss (68%) and practically infinite contrast at the Fabry–Perot resonance for an operating voltage swing of under 4 V.Keywords
