Enhanced electro-optic effects in suspended waveguides

We demonstrate enhanced electro-optic phase shifts in suspended InGaAs/InGaAsP quantum well waveguides compared to attached waveguides. The enhancement stems from tightened mode confinement between the electrodes, and should improve further with thinner waveguides.
