We had a great time at the annual MESA+ day at the Kinepolis cinema this week!
Steven and Akshay gave two well received talks, sharing our latest SBS discoveries and exciting progress in fabrication. Additionally, Tarik and Chuangchuang also did a great job with their posters, which drew a lot of attention.
Congrats to everyone for the nice presentations!
Last Friday, Prof. Cheng Wang from the City University of Hong Kong visited our lab. We showed him our lab and also the cleanroom at MESA+. Afterward, we had a fruitful discussion about our collaborations on thin-film lithium niobate.
We are excited to share our invited paper in the optomechanical photonics special issue of Optical Materials Express, titled “Brillouin nonlinearity characterizations of a high refractive index silicon oxynitride platform”.
In this paper, we explore the operating principles of an ultra-sensitive triple-intensity-modulated lock-in amplifier setup for Brillouin characterization, packed with a lot of practical experimental tips throughout.
Congrats Steven!
Prof. Michael Steel from the Macquarie University visit our lab this month. During his visit, we had a great discussion about our latest Brillouin photonics results, and he shared some really insightful feedback. Thank you for visiting us, Mike!
This week, we attended the 2024 European Conference on Integrated Optics in Aachen, Germany. We got the opportunity to present and discuss the latest progress happening in our group with four oral and three poster presentations.
Congrats all for these beautiful results!
We welcome Dharma Prasetya Permana to join our group as an intern for the next few months.
Dharma obtained his BSc in Physics from Bandung Institute of Technology (ITB), Indonesia in 2023. Before he starts his Erasmus Mundus Joint Master EuroPhotonics program in September 2024, he will work with Yvan on the four-wave mixing experiments in our group.
Good luck, Dharma! Hope you will enjoy your time here!
We are pleased to share a new publication of our paper at APL Photonics , titled “Observation of a Brillouin dynamic grating in silicon nitride waveguides”. In this paper, we report the first ever observation of Brillouin dynamic gratings in silicon nitride waveguides. Congrats Roel and Jasper!
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!
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.
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!
