Linear and nonlinear microscopy and spectroscopy
| Herman OfferhausWe explore linear and nonlinear interactions of light and matter and exploit the (phase) characteristics to extract useful information. Applications include label-free imaging of pharmaceutics and tissue, analysis of (ground) water electrolytes, detection of pathogens. The research focused on the use of nonlinear optical interaction to detect and control small amounts of specific molecules without using fluorescent labels. This was expanded to include microscopy and integrated sensing and detection. Most recently it expanded into pharmaceutical and medical imaging |

Fiber lasers and sensing
| Jose Alvarez ChavezMy research activities cover: High-power fibre lasers and amplifiers for medicine, telecomm, sensing and laser material procesing, and both theoretical and experimental work on passive and active fibre-based devices such as tapers. Our aim is to develop fiber based sensors and sources for industry, science and medicine. |
Dynamic nanophotonics
| Femi OjambatiMy reserach focuses on using plasmonic nanocavities to enhance light-matter interactions with bio-molecules. I use novel approaches to enhance optical fields at the nanoscale, for ultrasensitive sensing and to probe bio molecular dynamics. |
