摘要：

An optical GaAs/GaAlAs multiquantum-well vertical directional coupler switch with a device length of 85 mu m is presented. At a wavelength of 854nm the voltage necessary for switching was 5V, associated with a transmission loss of only 2dB in the switched state and an extinction ratio of greater than 10dB. The device parameters were chosen so as to enable monolithic integration.
