Abstract

Multiple quantum well (MQW) electro-optic modulators grown on both GaAs and InP substrates have been designed and characterized. Strained-layer (In,Ga)As/GaAs p-i-n diodes grown on (100) GaAs substrates were found to have a differential absorption coefficient of 3.7 × 103 cm-1 for an applied electric field of 6 6 × 104 V/cm. These (In,Ga)As/GaAs devices were also grown on (110) GaAs substrates and exhibited polarization sensitive electroabsorption. In addition, InGaAs/InAlAs asymmetric coupled MQWs were designed and fabricated. Real charge transfer kinetics between the coupled MQWs was exhibited by these devices.
