Information about the position

The PhD position focuses on studying optical spectroscopic, optomechnical, optoelectrical, and photochemical performances of metal/dielectric nanostructures, their metasurfaces or their hybrids with other types of materials. The research are closely related with all general topics in nanophotonics and plasmonics, or nanomanipulation. The potential applications of such investigation include, but not limited to, the construction of novel nanostructure-based optical elements (lens, beam-splitters, waveplates), the development of new types of optomechanical sensors and actuators for biology research, novel color displays, and ultrasensitive photodetectors.

The project is mainly experimental, but it can also involve simulation/theory and advanced nanofabrication. The tools in the study will be various spectroscopic imaging techniques (scattering, Raman, IR, fluorescence), laser tweezers, electrical tweezers, opto-electrochemistry characterizations, and electrodynamic/thermodynamic simulations.

The PhD student, if admitted, will be mainly supervised by Prof. Lei Shao (homepage link). Prof. Jianfang Wang (homepage link) will be a co-supervisor. The group has access to advanced optical microscopy/spectroscopy systems, as well as infrastructure for fabricating and characterizing structures at the micro/nanoscale. There is a close connection between experiments and theory. The group also has close collaborations with researchers in EU, Singapore, Australia, US, and mainland China. The postgraduate studentship will be over HKD16600/month. The potential students are also encouraged to apply for the Hong Kong PhD fellowship, which provides a studentship of HKD25100/month (please click here for more information of the Hong Kong PhD fellowship scheme).

Major responsibilities

The goal with a PhD-position is to develop general research proficiency and a high competence within your specific research area. As a PhD-student, you will primarily conduct research, often together with other researchers and PhD-students. You will also follow PhD courses, be involved in teaching activities or other departmental duties, and participate in international conferences and networks.

Your major responsibilities are to pursue your own doctoral studies and develop your independent research capabilities. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing, mainly in English. The position also includes teaching on CUHK’s undergraduate level or performing other duties.

Position summary

Full-time study, which is composed of a maximum of three (for applicants having a master degree from distinguished universities) or four (for applicants having a bachelor degree from distinguished universities) years full-time of doctoral studies, including teaching, equivalent to a maximum of 20 % of the total working time. The program is tied to successful completion of department evaluations after one or two years. The postgraduate studentship will be HKD16,600~25,100/month. The working language will be Putonghua or English.


To qualify as a PhD student, you must have a bachelor's or master’s level degree in physics, optics, engineering, nanoscience or a closely related field. We only accept students from 211/985 university with a GPA higher than 80/100 or 3.2/4.0. A good knowledge of optics and spectroscopy and a broad physics background is mandatory. Good skills at MATLAB, Labview, Python and/or C programming are meritorious. Experience from nanofabrication/laser experiments and experience with computational software (Comsol, FDTD Lumerical) and simulation tools are a plus, but not a must.

The position requires good communication skills in written English. Applicants who do not have English as their mother tongue need to provide documentation of good communication skills in English, typically evidenced by an English language test, for example TOEFL 550 (paper-based)/TOEFL 213 (computer-based)/TOEFL 79 (internet-based)/IELTS Band 6.5, and exemplified during the interview process prior to admission.

If you are qualified and feel interested, please contact Prof. Shao at
