Meta-Devices: From Sensing and Imaging to Quantum Optical Chip

19 April 2022


Professor Din-Ping Tsai

Professor Din-Ping Tsai, the Chair Professor of the Department of Electrical Engineering at the City University of Hong Kong (CityU), gave an online talk as part of the Hong Kong Institute for Advanced Study (HKIAS) Distinguished Lecture Series on Electronics and Photonics on 30 March 2022, titled "Meta-Devices: From Sensing and Imaging to Quantum Optical Chip". Professor Hon Yan, Wong Chun Hong Professor of Data Engineering was the moderator.

Metasurface technology is an advanced topic in flat optics that has recently attracted attention. In this talk, Professor Tsai discussed the fundamental principle, design, fabrication, and applications of the novel optical meta-devices, plus design principles and application prospects of meta-lenses.

Meta-lenses are flat lens technology made by optical components that use meta-surfaces to focus light. According to Professor Tsai, meta-devices using meta-surfaces composed of artificial nanostructures can manipulate the electromagnetic phase, polarization, and amplitude.

Recently, the versatile applications of meta-lenses have been demonstrated in polarization imaging systems, phase imaging systems, light-field cameras, and other multi-functional applications. Professor Tsai further elaborated with his latest innovative research, including the achromatic meta-lens array for full-colour light-field imaging and high dimensional quantum light source with the meta-lens array.

Microlenses are considered one of the top 10 emerging technologies for 2019. Professor Tsai stressed that meta-lenses demonstrate their tremendous potential for future applications, such as robotic vision, nano robots, mini-drones, virtual reality systems, and autonomous vehicles.

In conclusion, Professor Tsai believes meta-lenses with novel functions can be incorporated into many existing optical systems to achieve new features and a more compact configuration, giving rise to a new era of optical meta-devices.

Professor Din-Ping Tsai’s research interests are nanostructured semiconductor electronic and photonic meta-devices and systems for emerging electronics and high dimensional quantum optical information applications.
