Abstract :
Measurements of GaAs-AlGaAs multiple-quantum-well (MQW) reflection modulators grown simultaneously on GaAs and silicon substrates are presented. Comparable electroabsorption is observed, with contrast ratios of about 4:1 for both modulators at 20 V. The absorption spectrum of the GaAs-on-Si quantum well shows a single exciton peak, which leads to certain improvements in modulator performance. This study is very encouraging for the growth of GaAs MQW modulators on silicon integrated circuit chips for off-chip communication.<>
