Research Stories

A new vortex electric field with the potential to enhance future electronic, magnetic and optical devices has been observed by researchers from City University of Hong Kong (CityUHK) and local partners.

A pivotal breakthrough in battery technology that has profound implications for our energy future has been achieved by a joint-research team led by City University of Hong Kong (CityU).

A team led by a physicist from City University of Hong Kong (CityU) recently developed a new quantum theory that explains the “light-induced phase” of matter and predicts its novel functionalities.

A collaborative research team co-led by researchers from City University of Hong Kong (CityU) developed a new approach to generate deep-ultraviolet lasing through a “domino upconversion” process of nanoparticles using near-infrared light, which is commonly used in telecommunication devices.

In the era of Artificial Intelligence (AI), a novel optical “micro-comb” chip developed by a physicist from the City University of Hong Kong (CityU) has played a pivotal role in building the fastest optical neural network processor. An international research team has recently demonstrated the world’s fastest and most powerful optical neural network processor, which is capable of operating at faster than 10 trillion operations per second.

In the era of smart cities and amid the global outbreak of Covid-19, connecting through the internet is getting more important than ever. Researchers have been working day and night on advancing the optical data transmission network to address the demand for faster transmission speed. An international research team has developed a new technology that is equipped with a special chip made by a scientist from City University of Hong Kong (CityU). The team broke the spectral efficiency world record for optical data transmission with a single integrated photonic chip. This allows the transmission speed as fast as downloading 1,000 high-definition movies in less than a second!
