We are excited that two papers in our group have been accepted for oral presentations at CLEO 2022, San Jose, California, USA. They are:

• Roel Botter, et al., Stimulated Brillouin Scattering Microwave Photonic Notch Filter in Silicon Nitride
• Kaixuan Ye, et al., Optimization of Stimulated Brillouin Scattering Gain in a Double-Stripe Si3N4 Waveguide

We have a new publication in Optics Letters (OL) titled Self mode-locking in a high-power hybrid silicon nitride integrated laser.

In this paper, Yvan demonstrated  the self-mode-locking of a hybrid integrated laser comprising two indium phosphide gain sections and a silicon nitride feedback circuit that filters light using two ring resonators.

Okky has won the best paper award at the International Symposium on Modern Optics and Its Applications (ISMOA 2021). Congratulations 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 managed to break the egg and have the very first journal paper from the Nonlinear Nanophotonics group! Okky’s work on a programmable RF photonic bandpass filter in a silicon nitride circuit came out in OSA Continuum ! The article can be found here.

We have a new paper coming out in OSA Advances in Optics and Photonics in collaboration with the Eggleton group at Sydney University and the Choudhary UFO-Chip group at IIT Delhi. The paper reviews recent advanced in Integrated Microwave Photonic Filters ! The article can be found here.

Xin’s work on the Silicon Photonic Modulation Transformer has bee accepted as a postdeadline presentation at the Asia Photonics and Communications Conference (ACP 2019)! The work is a collaboration between our group and The Eggleton Group at University of Sydney, The Photonics Research group at Ghent University, and Microsoft Quantum University of Sydney.
