Introduction: Topic 1：

I will report on our group's recent results on three research streams: epsilon-near-zero physics, quantum optics in the infrared, and filamentation in air.

Epsilon-near-zero materials are an attractive platform to deliver nonlinear effects at a sub-wavelength scale, with potential applications in ultrafast computing and light manipulation. We will report on our studies on the origin of the enhanced non-linear effects in strongly coupled ENZ-plasmonic systems.

Quantum optics in the 2um region may impact free-space and guided quantum communication and metrology. We will report on our studies on quantum states generation, transport and detection in this spectral region. At longer wavelengths, quantum optics may deliver enhanced detection capabilities. We will present ongoing efforts that may enable quantum metrology to enhance the sensitivity of mid and far-infrared detection.

Finally, we will discuss recent results on laser filamentation in air at high repetition rates, where cumulative effects play a significant role.

Topic 2：

The invention of optical frequency combs, which was celebrated by the 2005 Nobel prize in Physics, has made great impacts on precision metrology, optical clockwork, molecular fingerprinting, amongst others. Recent advances in high finesse Kerr-active micro-cavity have provided a promising platform for study of cavity nonlinear dynamics and offered a reliable route towards the vision of chip-scale ultrashort pulses and frequency combs. Chip-scale optical frequency comb will become more instrumental in areas where compact footprint, low power consumption, large comb spacing, and access to unconventional spectral region are essential. In this talk, I will present our recent results on: i). the generation of Kerr soliton microcombs with ultra-low time jitter, and ii). using ultra-low phase noise Kerr combs for coherent data communications.

Speakers’ profiles：

Dr Clerici is Professor of Photonics and leads the Ultrafast Nonlinear Optics group (UNO) at the University of Glasgow, a team of one post-doctoral researcher and six PhD students. The group research mainly focuses on quantum optics in the visible and infrared spectral region, THz photonics and epsilon-near-zero physics. Dr Clerici is the author of ~70 publications, ~60 invited talks, and >130 conference contributions. He obtained an MSc in Physics in 2006 and a PhD in Physics in 2010 at the University of Insubria. He was FQRNT Fellow (2011-2012) and Marie Curie Fellow (2012-2015) at the INRS-EMT in Canada and Heriot-Watt University in the UK. He was then a Lecturer (2015-2019), Senior Lecturer (2019-2022) and Professor (2022) at the University of Glasgow. Clerici was the recipient of the 2014 Sergio Panizza award from the Italian Physical Society for his contribution to THz photonics.

Dr. Heng Zhou is now an Associated Professor at School of Information and Communication Engineering, UESTC. His researches focus on Nonlinear Optics, Ultrafast Optics, and Optical Communications, with 50+ publications on Nat. Comms, Light: Sci. &App, Phys. Rev. Lett, etc. His innovations, including technique for Kerr soliton microcombs generation circumventing cavity thermal effect, and coherence-cloning frequency combs over long fiber link for coherent transmission, are now widely used both in academic research and industry applications.
