About Us

The Photonic Devices Group operates at the Department of Electronics, Information and Bioengineering of the Politecnico di Milano since 1996.
Our prime competences are in passive and nonlinear integrated optical circuits on both low index contrast and high index contrast platforms.
We are researching to increase the scalability of Photonic Integrated Circuit while reducing the design complexity.

We are on Light: Science & Applications

We are proud to announce that our work “Separating arbitrary free-space beams with an integrated photonic processor” has been published on Light: Science & Applications Abstract: Free-space optics naturally offers multiple-channel communications and sensing exploitable in many applications. The different optical beams will, however, generally be overlapping at the receiver,…
