Electromagnetic study of an electronic sampler for picosecond pulse measurements

This paper deals with an optoelectronic sampler whose expected time resolution is 5 ps (corresponding to a bandwidth up to 50 GHz). The sampler device is made up of metallic stripline combined with fast photoconductor thin film. This device is studied along two interacting directions: 1) sampler description and operation 2) electromagnetic study In particular, the electromagnetic study is discussed here. The purpose of this study is to understand the electromagnetic behaviour of the optoelectronic sampler.
