Photonic Crystal Fibers: Investigation of the interaction of light and single emitters in nanostructured glas

The goal of this project is to detect the fluorescence of single emitters, such as single molecules, nanocrystals, colloidal particles, and labeled (bio-)molecules in solution within photonic crystal fibers (PCFs). The interaction between single emitters and PCFs will be investigated both qualitatively and quantitatively. More precisely this means the investigation of fluorescent proprties of single emitters in PCFs (modification of absorption and emission rate of dye molecules, nanocrystals, doped colloidal particles and labeled (bio)molecules), the demonstration of the modification of light transmission through PCFs by single emitters (phase shift, birefringence), time resolved measurements of fluorescence in PCFs (using the dispersion in order to derive spectral information via time resolved measuerements), functionalization of PCFs, demonstration of micro- and nanotransport of liquid through PCFs, investigation of light forces acting on dielectric particles, and control of transport via light in a combination of PCFs and commercial microflow devices. As a proof-of-principle experiment of a new concept a single labeled cell or a single macromolecule will be injected in a PCF via light force and detected via its guided fluorescence with high selectivity and specifity.
