« Silicon photonics for optical communications and mid-IR spectroscopy »

Pr. Delphine MARRIS-MORINI (C2N)

le 28 novembre 2017 de 10h30 à 12h30, à l’Enssat de Lannion (amphi 137C)

Silicon photonics has generated a strong interest in recent years, first mainly for optical telecommunications and optical interconnects in integrated circuits. The main rationales of silicon photonics are the reduction of photonic system costs and the increase of the number of functionalities on the same chip combining photonics and electronics. Recent advances in silicon photonics optoelectronic devices will be presented with a focus on optical modulators and photodetectors for the demonstration of high performance optical transceivers.

The extension of silicon photonics towards the mid infrared (mid-IR) spectral range has also recently attracted a lot of attention. The development of photonic devices operating at these wavelengths is crucial for many applications including environmental and chemical sensing, astronomy and medicine. Recent works regarding the development of new photonics platform on silicon will be presented.
