Infrared Emitting Erbium-Doped Quinolines for Silicon Organic Hybrid Technology

The emerging application of organic materials to the integrated photonics led to the definition of the Silicon Organic Hybrid (SOH) technology, that is a promising approach to bring active functionalities on an intrinsically passive silicon substrate. Erbium-doped molecular materials were demonstrated to provide IR emission in the C band when grown on silicon as solution processed thin films, enabling potential low cost processing of organic sources integrated on silicon. The contribution is meant to provide an overview of the recent results of the molecular enhancement of the Er-doped quinolines as IR emitters and their application into a slot waveguide structure designed over a SOI platform for compatibility to standard CMOS processing technologies.
