    Abstract

    We report a 27:l switching contrast ratio with 2.5 mW of power in an asymmetric Fabry- Perot Ctalon. The modulation is achieved by optical saturation of the excitonic absorption profile of a 95 A GaAs/AlGaAs multiple quantum well structure grown on a high-reflectivity dielectric stack mirror.
