Photonic integration for millimetre-wave and THz systems

Photonic technologies have a large potential to become the key enabler for millimetre-wave and THz application. Despite a number of advantages such as tune ability, high speed modulation and high coherence across the range, a number of issues still remain to be solved in terms of efficiency at emission and detection and power. We propose that photonics integration is key to help solving these problems. We will first present the key advantages of using photonic integration for this particular application, then discuss the different technologies that could be envisaged. Finally we will present recent integration results and discuss the achievements in regard of a few potential millimetre-wave and THz applications.
