Abstract
The group velocities in coplanar strip transmission lines on Si and Si/SiO2/Si substrates were compared experimentally and theoretically. To ensure the experimental accuracy, a differential electro-optic sampling system with a delay-time resolution of 30 fs and a spatial resolution of 1 μm has been developed. Compared with the group velocity on a Si substrate, the group velocity on a Si/SiO2/Si substrate with a 2.2 μm SiO2 layer was found to be 10% faster, which agrees well with the theoretical prediction.
