Light–matter interaction in nanostructures and the integration of optical and electro-optical technologies on the Si platform are research fields that receive strong and growing attention and that are relevant for a broad range of application areas, from imaging to quantum computation. Here, we put a focus on their intersection with the discussion of device concepts, challenges, and opportunities for the integration of nanophotonic structures into optoelectronic devices on the Si platform. The incorporation, in particular, of metasurfaces into optoelectronic devices offers unique possibilities not only for adding device functionality and improving efficiency at the same time but also for material integration, provided that the challenges associated with device integration can be addressed.
