In this paper, we present a novel ultra-high-speed polymer based electrooptic modulator that features a profiled, deeply etched cross section. We show that by profiling the side walls of the modulator and varying the thickness of the dielectric stack that broadband operation can be achieved whilst maintaining a very low drive voltage in a compact device. Initially a quasi-TEM analysis is undertaken in order to determine the modulator's response to topographical variation followed by a full-wave analysis on the optimized device. The full-wave analysis is employed in order to determine any frequency disperson effects with respect to the modulators characteristic impedance Zc, microwave effective index Nm, microwave and dielectric losses alpha-c and alpha-d, and the half-wave voltage-length product VnL.
