On August 6th, Roland Adelerhof defended his MSc thesis titled Numerical Investigation of Surface Acoustic Waves in a Silica Ridge Waveguide for Optical Modulation under the supervision of Radius.
Roland presented in a hybrid in-person and online defense. After the defense he received a present from the whole group. Congrats Roland!
Okky has won the best paper award at the International Symposium on Modern Optics and Its Applications (ISMOA 2021). Congratulations Okky!
David delivered the inaugural May-On Tjia lecture at the International Symposium on Modern Optics and Its Applications (ISMOA 2021). This is a lecture to commemorate Prof. Tjia, who is a giant and influential figure for Indonesian physics community. In this 45 minute lecture, David recalled some past experiences with Prof. Tjia and went on to discuss state-of-the-art of programmable photonic circuits. You can watch the recording of the lecture here.
We are excited that Okky’s paper has been accepted for an oral presentation at ECOC 2021, Bordeaux. The paper is also selected as highly-scored paper. Congrats Okky!
We have a new publication in Journal of Lightwave Technology (JLT) titled Integrated microwave photonic spectral shaping for linearization and spurious-free dynamic range enhancement. In this paper, Gaojian demonstrated two novel linearization techniques using serial and parallel arrays of silicon nitride ring resonators.
We have a new publication in APL Photonics titled Versatile silicon microwave photonic spectral shaper. This was a collaborative work between our group, The University of Sydney, and Ghent University. The article has been selected as Editor’s pick, and can be found here.
There’s a nice news item on this article appearing at the University of Twente website and PhysOrg.
We have been ramping up in our research activities on integrated microwave photonics spectral shaping. We have three new papers appearing in Journal of Lightwave Technology (JLT), Optics Express, and Optics Letters.
In JLT paper we present an invited tutorial on the new concept of Integrated Microwave Photonic Spectral Shaping. The article can be found here.
In the Optics Express paper, Gaojian demonstrated that line-by-line spectral shaping using ring resonators can be used to linearize the transfer function of a microwave photonic link. The paper is titled Linearized Phase Modulated Microwave Photonic Link based on Integrated Ring Resonators and the article can be found here.
Finally, in the Optics Letters article, Okky demonstrated a Microwave Photonic Notch Filter with Integrated Modulation Transformation and Optical Carrier Suppression all integrated in a silicon nitride circuit. The paper can be found here.
We recently have three very successful student graduations!
First, on January 28th Thomas Zeinstra defended his BSc thesis titled Programmable Microring Resonator with Double Injection in Silicon Nitride, under the supervision of Okky.
On February 1st, Pieter van Essen defended his BSc thesis titled Stimulated Brillouin Scattering in Silicon Nitride using a Racetrack Resonator under the supervision of Yvan.
Finally, on February 12th Max Kiewit defended his MSc thesis titled Integrated Brillouin Lasing in Cascaded Double Ring Resonators under the supervision of Roel.
After the online defense all three students received presents from the whole group. Don’t finish them in one go guys! 🙂
Our group had our online end of year celebration! Let’s hope for the best for 2021!
Exactly two years ago to the day, our group had our very first operational experimental testbed (see News from Sept. 14th, 2018 below). At that time our group consisted of only two people (David, and Okky as an intern). Now we are 13-people strong with 7 operational testbeds. O how we’ve grown!
