Abstract :
The quantum-confined Stark effect in strained InGaAsP multiquantum wells with InGaAsP barriers and its application to the optical electroabsorption waveguide modulator are described. A large spectral red shift of more than 450 AA is observed at a low applied voltage of 3 V. An extinction ratio of >14 dB is demonstrated with a driving voltage as low as 5 V.
