Photonic Integrated Circuits for Terahertz Communication: The Hybrid Integrated Microwave Photonic approach

Optical heterodyne signal generation is the most flexible photonic microwave generation technique. Photonic integrated solutions have been shown monolithically on InP, and more recently on silicon. We present novel implementations using hybrid integration technology with silicon nitride (with high-Q resonators for extremely low linewidth) and polymer (with low permittivity material for highly efficient radiation).
