摘要
对ps级超短电脉冲测量而言,电光取样是目前最准确、最有效的方法之一。本文介绍了电光取样的基本测量原理及实验途径,对测量的误差因素进行了分析。电光取样对由电光晶体如GaAs、LiNbO_3等制成的光电器件的瞬态响应测量具有特殊优点。本文着重对GaAs集成电路的瞬态测量原理和方法及误差因素进行了介绍。电光取样基于谐波混频原理对GaAs高频场分布的测量也十分有效。
At present, electro-optic sampling is one of the most useful and accurate ways to measure picosecond electrical signals. An introduction (?)s involving the basic principle of E-O sampling, the realistic testing, its sensitivity and its time resolution, etc. The technique has its superiority when it is used in characterizing the response of some ultrahighspeed devices made of electro-optic crystals. A measurement of the GaAs integrated circuit which is involved in its experimental principle and its circuit perturbation is discussed. The E-O sampling is also very useful in studying the distribution of high frequency electric field in some electronic and optoelectronic devices made of GaAs, LiNbO_3, InP, etc.
