Research showcase
Highlights of the recognition and reach of the Emergent Photonics Research Centre.
Our research is widely published in the most prestigious journals, and we are invited to present our findings at conferences worldwide. In 2022, our Director was elected as an Optica Fellow, acknowledging his contribution to advances in the field of optics.
High parametric efficiency in laser cavity-soliton microcombs
This open access article details how we theoretically and experimentally study the soliton conversion efficiency between the narrowband input pulse and the two outputs of a four-port integrated microcavity, namely the ‘Drop’ and ‘Through’ ports.
We simultaneously measure on-chip, single-soliton conversion efficiencies of 45% and 25% for the two broadband comb outputs at the ‘Drop’ and ‘Through’ ports of a 48.9 GHz free-spectral range micro-ring resonator, obtaining a total conversion efficiency of 72%.

Self-emergence of robust solitons in a micro-cavity
This open access article details how we overcame a major obstacle in the development of portable atomic clocks - namely, how to reliably activate their counting device and keep it running.
It was published in collaboration with colleagues at the University of Sussex, City University of Hong Kong, the Xi’an Institute of Optics and Precision Mechanics (China), Swinburne University of Technology (Australia), the Institut National de la Recherche Scientifique (INRS, Canada), and the University of Strathclyde.

Centre Director elected as Optica Fellow
Professor Marco Peccianti was among the 2022 cohort, elected to Optica’s prestigious Fellows for sustained pioneering contributions in the field of optical complexity and the development of novel terahertz applications based on ultrafast nonlinear photonics.
The number of elected Fellows does not exceed 10% of the total number of Optica members across the globe, and the number of members elected each year is only about 0.5% of the current total.
Formerly OSA, Optica is a professional international authority in the field of optics in the United States.
