We report on the hybrid integration of silicon-on-insulator slot waveguides with organic electro-optic materials. We investigate and compare a polymer composite, a dendron-based material, and a binary-chromophore organic glass (BCOG). A record-high in-device electro-optic coefficient of 230 pm/V is found for the BCOG approach resulting in silicon-organic hybrid (SOH) Mach-Zehnder modulators that feature low UĈL-products of down to 0.52 Vmm and support data rates of up to 40 Gbit/s.
