摘要
本文报道了共轴反射式电光取样系统。该系统时间分辨率不低于20ps,空间分辨率不低于3μm。用它检测了砷化镓共面波导内部的微波信号。这套系统将被应用于砷化镓高速集成电路内部特性的在片检测。
A coaxial reflection-mode electrooptic sampling system is presented. This system has a temporal resolution less than 20 ps and a spatial resolution less than 3μm. The internal microwave signals in GaAs coplanar waveguides have been probed by the system. This system will be apply to on-wafer tests of internal characters of GaAs high-speed integrated circuits.
