Ph.D. SMIEEE, SMOSA

Lecturer (Assistant Professor)

Dept. of Electronic & Electrical Engineering

University College London, London, UK

Thanks for your visit. I am a lecturer and a member of the Optical Networks Group at the EEE Department at UCL. My research focuses on optical systems and instruments for high-performance data centre interconnection and signal processing. Our work brings together optical, electronic, and software techniques to overcome the fundamental limit in optoelectronic systems, aiming 5-10 years prior industrial applications.

We welcome students and researchers join us in our exciting research projects. Please contact me for PhD and postdoc opportunities.

ECOC postdeadline reporting sub-nanosecond CDR recovery

September 26, 2018

In collaboration with Microsoft, we demonstrate our 'phase caching' technique in the post-deadline session of the 2018 European Conference of Optical Communications (ECOC). Our phase caching technique achieves <625ps clock and data recovery locking time that for 25.6Gb/s-OOK signals. The locking time was improved by 12×, making nanosecond optical switching viable in data centres.

Direct detected PAM4 for long-reach system_OFC 2018

March 30, 2017

In OFC 2018, we report on 4×112Gb/s direct-detection PAM4 transmission over 300-km standard single mode fiber. The advantage of our proposed transmitter is that it requires minimum digital signal processing (DSP) for chromatic dispersion compensation only. Thus it has the potential for low-power consumption and low latency transmission for inter-DC or Metro networks. Please read our paper for details. (OFC'18 W1J.6) paper

OFC2017 postdeadline report record capacity over HC-ARF

March 30, 2017

In standard optical fibre, light pulses that carry data travel through a glass core. In contrast to standard fibre that guides light by total reflection, hollow core fibreLead guides light in an air core and comes in two fundamentally different guidance mechanisms. By Dr Zhixin Liu, researchers at ULC and the ORC at Southampton University have contributed to a new record data transmission 6.8Tbit/s in a type of fibre called antiresonant hollow core fibre. Check our press release here.
