Integrated multiple-quantum-well/Fabry-Perot structure provides high-contrast variation of reflection of reading beam, under control of writing beam. Periodic potential barriers separate photogenerated electrons from holes, leading to long recombination lifetimes and large concentrations of free charge carriers. Concentrations quench excitons or fill energy bands in quantum wells, altering absorption of reading beam.
