New publication in Science Advances

We are excited to announce that our new paper Guided-acoustic stimulated Brillouin scattering in silicon nitride photonic circuits has been published in Science Advances.

In this work, we use the symmetric double-stripe silicon nitride waveguide from LioniX to guide both the photon and phonon, showing the possibility to integrate stimulated Brillouin scattering in large circuits. This breakthrough will potentially be integrated with other emerging technologies such as tunable lasers, frequency combs, and programmable photonic circuits, and giving them a part in the future development of fields ranging from telecommunications to quantum computing.

This publication is a great achievement for Roel, and of course, also for the whole team. Congrats all!

Jasper, Sam, and Lou Graduated

Three very brilliant students graduated from our group recently!

First, on July 8th Jasper van den Hoogen defended his MSc thesis titled Brillouin dynamic gratings in a silicon nitride waveguide, under the supervision of Roel and Steven.

On July 11th, Sam Rappange defended his BSc thesis titled Programmable double injection coupled ring resonators for microwave photonic signal processing under the supervision of Okky.

Finally, on July 12th Lou Kanger defended his MSc thesis titled Generation of Kerr frequency combs for microwave photonics under the supervision of Yvan and Okky.

After the defenses, all three students received presents for their great work. The whole group also had lunch together to celebrate graduations and the coming of summer holidays.

ERC Consolidator grant for David Marpaung

David received the ERC Consolidator grant for the project TRIFFIC. He  will develop an new class of 3D photonic integrated circuit for actuating stimulated Brillouin scattering in silicon nitride. With this entirely novel circuit, he will show for the first time that interactions between light and sound can also be programmed, just like for electronic circuits. 

David will receive 2.55 million euros for his project, the largest Consolidator Grant so far in Twente, and third-largest ever in The Netherlands.

New funded project from ARC

Our group, as a partner for the RMIT University in Australia, recently get the Discovery project 2022 funded by Australian Research Council (ARC).

This project will focus on developing new microwave photonic systems based on acousto-electric phonon-amplified SBS.  The official announcement of this project at the ARC website can be found in this  link.
