Transmission-line Characterization With Ultrafast Optoeletromes

Summary form only given.Recent advances in the characterization of resistive transmission lines by optoelectronically - generated ultrashort electrical pulses will be discussed. Resistive transmission lines are those in which dielectric losses are negligible, and where attenuation is dominated by losses in the metallic interconnections. Circuit-to-circuit wiring on large integrated circuits and in most modem electronic inter-chip interconnection structures are examples of resistive transmission lines. So are the coplanar waveguides and microstrip lines, fabricated on insulating substrates, commonly used in microwave hybrids.
