Description

Dr Chu Sai-tak, Associate Professor in the Department of Physics from City University of Hong Kong (CityU) has played a pivotal role in advancing data transmission speed on the internet to make it the fastest in the world.

Such speed will facilitate downloading 1,000 high-definition movies in less than a second, according to the international team that undertook the research.

The team’s accomplishments were recently published in Nature Communications under the title “Ultra-dense optical data transmission over standard fibre with a single chip source”. The team comprises researchers from Australia, Canada, mainland China and Hong Kong.

Dr Chu is an expert in integrated photonic devices and with over 30 years’ research experience, his research on chips has contributed to twelve high-impact papers published in the past nine years in prestigious journals such as Nature and Science.

TitleNew chips accelerate data transmission
DescriptionDr Chu Sai-tak, Associate Professor in the Department of Physics at City University of Hong Kong (CityU) has developed a novel chip that advancs data transmission speed on the internet to make it the fastest in the world.

This research innovation demonstrates the capacity of micro-combs, which are optical frequency responses based on micro-ring resonators (MRRs), to perform ultra-high optical data transmission. Its accomplishments were recently published in Nature Communications under the title “Ultra-dense optical data transmission over standard fibre with a single chip source”.

The team will further explore scaling down the overall bandwidth by using multicore fibre as well as minimising the optical components by integrating the chips with modulators, for example.
