Abstract
Electroabsorption in an InGaAs/GaAs strained-layer multiple quantum well structure has been observed. With only ten quantum wells, 6.4% transmission modulation was obtained at 0.950 μm with 2 V reverse bias. A single absorption peak was observed, in contrast to the double peak observed in similar GaAs/AlGaAs structures. The present structure is fabricated on a GaAs substrate which is transparent to light at the exciton absorption wavelength.Keywords
