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.

Our paper is in the editor’s highlights on Nature Communications!

We are excited to announce that our paper” Polarization-transparent silicon photonic add-drop multiplexer with wideband hitless tuneability” has been featured in the 50 best paper recently published in the “Optics and photonics” area. The editors routinely replace papers as more great research is published at Nature Communications.  Link to the editor’s…

We are on Nature with Photonic Chips for broadband connections

The first TOADM (Tunable Optical Add Drop Multiplexer) device capable of selecting and routing signals in network nodes in a purely optical manner, built on a silicon chip of only 2 mm2, has been demonstrated. The result, that will enable the growth of broadband in the optical networks of new 5G/6G communication systems…

First Polimi Photonic Integrated Congress

In the context of the Photonic Devices course held by Professor Melloni, the students had the opportunity of organizing and partecipating to a congress. Four students of the course, helped by our Ph.D. Christian De Vita, were elected as members of the Steering Committee while other students partecipated as researchers….
