Welcome

Thank you for visiting Photonics and Laser Engineering Laboratory at Bangor University, North Wales, UK. The team is led by Professor Zengbo (James) Wang, focusing on the development of next-generation photonics and laser technologies for wide ranges of applications in advanced manufacturing, super-resolution imaging, sensing, solar cell devices, among others.

One key scientific achievement by us is the pioneering of ‘microsphere nanoscope’ and super-resolution techniques and applications based on dielectric particle superlenses made from microspherespider silk  , high-index nanoparticle and others. These were widely publicised. Check our featured  interview (“Improbable vision“)   and review chapter (Super-resolution imaging and microscopy by dielectric particle-lenses“)  we wrote about the technique.   

Despite the commercial models are now available, their performance is still quite limited and suffers from limitations including low contrast, slow-speed, sample-dependent imaging quality and extreme-short working distance which all need to be addressed carefully with innovative solutions – we are leading many important innovations in solving these challenges (roadmap and Roadmap on Label-Free Super-resolution Imaging).

Our team also actively works in nanophotonics and metamaterials (e.g. ‘anti-laser’ filter), laser material processing (e.g. artificial surface,  nano-marking) and solar energy, with wide applications in industry.
