摘要：

We report on the first 2X2 GaAs asymmetric Mach-Zehnder interferential switch. The mechanism of this device is analyzed. Instead of using Y branches, two asymmetric X junctions have been utilized in the switch. The device is characterized by a switching voltage of 12.5 V and a crosstalk ratio of less than -22 dB at an operating wavelength of 1.15-mu-m. It is shown that this device could be applied to switching arrays.
