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.

3D illustration of the concept of trapping photon and phonon in multilayer silicon nitride waveguides

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!

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.

Four oral presentations at MWP 2021

We are excited that four papers in our group have been accepted for oral presentations at MWP 2021, Italy. They are:

Congratulations all!

Optical spectrum and transmission of the Vernier filter (Yvan)
Experiments setup (Okky)
Operating principles of the notch filter and linearization (Gaojian)
Optical and acoustic profiles of the ADS and SDS waveguides (Roel)

David has been awarded the NWO START-UP grant 

David has been awarded the START-UP grant of 800,000 Euros by the science division of the Netherlands Organisation for Scientific Research (NWO). The START-UP programme is intended for newly appointed faculties working in the field of physics and chemistry.

The 4-year project will focus on new ways of controlling gigahertz phonons using integrated photonics. There will be several open PhD and postdoc positions in this project, so if you’re interested please contact David.
