Paper Abstract

A new rnethod, based on zero point of longitudinal electric field, was used to deterrnine the spatial resolution of electro-optic (EO) probing systern. To examine the spatial resolution of internal and external EO probing systems, an interdigital structure is fabricated on GaAs substrate with and without a layer of Si02 between the electrode and the substrate respectively. Considering Si02 layer or air gap between electrode and EO crystal, the result of electro-optic probing was simulated which is well accorded with experiment. The result indicates that spatial resolution of less than 0.5um and lum are obtained in internal and external EO probing system respectively.
