Welcome

Thank you for visiting Laser & Photonics Research team at Bangor University, North Wales, UK. The team is led by Dr. 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 commercial models are now available, their performance are still quite limited and suffer 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 of important innovations in solving these challenges (roadmap).

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.
