University of Warsaw

Structured optics and optofluidics group

The team at Faculty of Physics at University of Warsaw shall utilize their extensive expertise in glass processing and hollow core optical fiber research to deliver the QUNNA Consortium experimental backbone in form of either bulk glass or specialty hollow core fiber platforms functionalized with NDs, or with hollow core fibers or laser written glass waveguides for micro-opto-fluidic sensor applications. In addition to their competence in structured optical fiber development and modeling, the Group shall use their experience in generation and characterization of femtosecond (roughly 100 parts of a millionth of one billionth of a second) laser light pulses in time-resolved spectroscopy of SiV and NV color centers in nanodiamonds. In combination with our QUNNA Partners from Jagiellonian University, Gdańsk University of Technology and Institute of Biotechnology and Molecular Medicine, we have the ambition to address current challenges in high sensitivity, optofluidic diagnostic tools for detection of cancer cells or hazardous chemical agents in small volume samples. We furthermore look forward to combining our Partners’ expertise in nanodiamond fabrication with our experience with specialty fiber optics to explore and to widen the current limits of pure silica hollow core fibers in ultrafast and nonlinear optics applications.
