Roel graduated

April 5, 2024Uncategorizedstevenkye

On March 25th, Roel successfully defended his Ph.D. thesis titled “Stimulated Brillouin scattering in silicon nitride based waveguides”.

Roel’s contributions to research in our group over the past few years have been remarkable. He unlocked the first on-chip stimulated Brillouin scattering signal in our group. Additionally, he advanced the SBS signal by employing tellurite-covered silicon nitride waveguides. Furthermore, he explored new Brillouin-based applications, i.e. Brillouin dynamic gratings.

Roel will start his new career as the integrated optics system architect at LioniX. Congrats, Roel! And good luck!

WOMBAT workshop

February 18, 2024Uncategorizedstevenkye

Last week, Yvan and Steven attended the 5th International Workshop on OptoMechanics and Brillouin-Mandelstam Scattering (WOMBAT) in Campinas, Brazil.

It is an outstanding workshop with a lot of interesting talks. From our side, Yvan contributed an oral contribution about SBS in the tellurite-covered silicon nitride waveguides. In the meantime, Steven presented a poster about the overview of the SBS characterization activities in the scalable photonic integrated platform.

Roadmapping day 2024

January 19, 2024Uncategorizedstevenkye

The first NLNP roadmapping day was successfully held on January 19, 2024. We summarized the research activities in the last year and discussed goals for the near-term and long-term future. It is a truly fun day filled with new ideas and nice food. Thanks, Zheng and Carla for organizing it!

ERC Proof of Concept grant

January 18, 2024Uncategorizedstevenkye

Our group is awarded the prestigious ERC proof of concept grant for the project Veritas. We will receive 150k euros for this project to develop versatile, reconfigurable light sources in photonic integrated circuits. Congrats, the Veritas team!

This news also appears at the University of Twente website.

Randy graduated

December 15, 2023Uncategorizedstevenkye

On December 15th, Randy te Morsche successfully defended his Master’s project on “Stimulated Brillouin scattering and lasing in tellurite-covered silicon nitride photonics”. He worked on this project with his daily supervisor Yvan Klaver, and they have made great progress together.

Congrats, Randy! Enjoy your short break before rejoining us for the Ph.D. project next year!

Lou received KHMW Young Talent Graduation Award

December 6, 2023Uncategorizedstevenkye

Lou Kanger, a former master student from our group, received the KHMW Young Talent Graduation Prizes for his master’s project on optical frequency combs. Lou explored frequency combs integrated on a single chip and developed innovative ways to test them for applications in next-generation radio communication.

Currently, Lou works at Enlightra, a start-up company in the field of frequency combs in Switzerland. Prior to his departure to receive the prize, he also gave us an exciting presentation about the latest progress in optical frequency combs and a live demo of the up-to-date prototype from Enlightra.

Congrats Lou! We are so proud of you!

On November 9th, Jitse Boonstra successfully graduated from our group with Bachelor degree. He worked with Zheng on “Calibration and control of cascaded microring resonators using Extremum Seeking Control” for the last two months.

Congrats, Jitse!

Jitse received beers from David as the graduation gift

David’s inauguration-And light said:”Let there be sound!”

September 28, 2023Uncategorizedstevenkye

On September 28, 2023, David hosts his inauguration ceremony for being promoted to full professor and the chair of the Nonlinear Nanophotonics group at the Faculty of Science and Technology, University of Twente.

During the inauguration ceremony, David gave the lecture And light said: “Let there be sound!”. Group members of NLNP and LPNO, colleagues within the university, guests from the Netherlands and other countries in Europe, and friends and family from Indonesia, all joined the event to celebrate this big moment with David.

Congratulations, David! Wish both the light and sound will always resonate with you!

Aldi finished his internship in our group

August 22, 2023UncategorizedGraduationsstevenkye

On Augest 22th, Aldi Fadhilah finished his half-year internship in our group. He worked on the stimulated Brillouin scattering in silicon oxynitride photonics waveguide and its potency for the implementation of Brillouin dynamic grating under the daily supervision of Steven.

Based on his work during the internship, he passed his M.S. defense at the University Jean Monnet with flying colors. Aldi will continue his study as a Ph.D. student at the Technical University of Denmark. Good luck, Aldi! Wish you all the best during your Ph.D.

*Aldi brought cake*s to share at the farewell party
