Nanophotonic modulators and photodetectors are key building blocks for high-speed optical interconnects in datacom
and telecom networks. Besides power efficiency and high electro-optic bandwidth, ultra-compact footprint and scalable
co-integration with electronic circuitry are indispensable for highly scalable communication systems. In this paper, we
give an overview on our recent progress in exploring nanophotonic modulators and photodetectors that combine the
specific strengths of silicon photonic and plasmonic device concepts with hybrid integration approaches. Our work
comprises electro-optic modulators that exploit silicon-organic hybrid (SOH) and plasmonic-organic hybrid (POH)
integration to enable unprecedented energy efficiency and transmission speed, as well as waveguide-based plasmonic
internal photo-emission detectors (PIPED) with record-high sensitivities and bandwidths.
