Abstract
A set of high quality Zn1-xCdxSe/ZnSe quantum well structures with var ious well widths and Cd contents as well as Zn1-xCdxSe epilayers are g rown by molecular beam epitaxy. Their optical properties are investiga ted by measuring photoluminescence, reflection, and transmission as a function of a vertically applied electric field. The quantum-confined Stark effect is observed at 5 K and a change in transmission of more t han 30% achieved at 300 K. By means of numerical model calculations, t he underlying electro-absorption and electro-refraction spectra are de duced and the field-induced change of the relevant exciton parameters (resonance energy, oscillator strength, broadening) derived.
