AlGaN/GaN based electroabsorption modulator operating at fiber-optics telecommunication wavelengths

The intersubband transition in quantum wells was investigated from the viewpoint of application to operate at fiber-optics telecommunication wavelengths at low switching powers. For this purpose, we have simulated an electroabsorption modulator for (

=1.55
mu
m) based on Stark shifting an intersubband resonance in AlN-GaN-AlGaN-AlN step QWs which can operate at fiber-optics telecommunication wavelengths with low applied voltage.
