  • (in order of importance): optical interconnects;
  • silicon photonics;
  • optical waveguides;
  • silicon modulators;
  • germanium photodetectors;
  • hybrid lasers;
  • photonic–electronic integration


We present possible technologies for on-chip optical interconnects integrated with electronics. We first describe the requirements for an optical link and the architectures that can be used for high-speed parallel optical links and optical networks on chip. We then give a more detailed overview of the optical building blocks, with a strong focus on silicon photonic implimentations: waveguides, wavelength (de)multiplexers, modulators, photodetectors and also the possibility of integrated lasers. Finally, we discuss the different options for integration of the photonic interconnect layers with electronics.
