Abstract

This project will involve theoretical and experimental characterization of capacitively-induced free-carrier effects in silicon waveguides. We anticipate our results to show that, in addition to being a critical factor in the analysis of such active Si photonics devices as capacitively-driven silicon modulators, this effect should also be taken into account when considering the propagation losses of passive silicon waveguides.
