Abstract
The experimental results of a 4 μm-thick GaAs/AlGaAs MQW modulator show an ~10:1 on/off ratio with an applied voltage of 20 V (Δα~6×103/cm at E ~50 kV/cm) and ~0.4 πrad of phase shift with an applied voltage of 10 V (Δn ~0.04 at E ~25 kV/cm). Such high electro-optical modulations have previously been reported only in MQW optical waveguide modulators
