摘要
建立了基于１．３μｍ增益开关分布反馈式（ＤＦＢ）半导体激光器的外电光采样系统．通过微小的ＬｉＴａＯ３电光探头做为电场传感器，实现了对具有重复频率的快速电脉冲波形的光学采样测量．实验测量了光电器件的脉冲响应及微带传输线上的梳状波波形．系统的性能分析表明该系统具有１８ＧＨｚ的带宽．
An external electro optic sampling system using a LiTaO 3 tip with a gain switched DFB laser diode was described. The 1.3μm ultrashort optic pulses were used to perform electric pulses via the Pockels effect in LiTaO 3 tip. The response curve of a high speed detector and the propagation dispersion of a coplanar strips were measured by this system. The bandwidth of 18GHz was confirmed with this system.
