Electro-optic phase modulation in GaAs/AlGaAs quantum well waveguides

We present the first absolute measurements of the electric-field-induced refractive index change in GaAs/AlGaAs quantum well waveguides. Phase and intensity modulation are characterized as a function of wavelength both above and below the n=1 exciton resonances.
