| Abstract: | We have investigated the electric field optical modulation of GaAs/AlGaAs multiple quantum well(MQW).Reflectivity,photocurrent spectroscopy and photocurrent voltage characteristics have been measured.The I V curve shows the feature of negative differential photoconductance.We have successfully fabricated the self electro optic effect devices(SEEDs)based on the MQW p i n structure and observe the obvious quantum confined Stark effect(QCSE)caused by room exciton absorption. |
