Abstract :
In this paper, we propose a novel potential-tailored quantum well which we believe is the simplest and can easily be fabricated by molecular beam epitaxy (MBE). We show theoretically that polarization dependence of MQW-EA (multiple quantum well electroabsorption) modulators can be drastically reduced by this new quantum well. All quantum wells in this paper consist of 0.4%-tensile-strained-InGaAs wells and lattice-matched-InAlAs barriers on InP since the tensile strain helps achieving the polarization independent operation in this work
