Taking into account all advantages of the resonant waveguide grating (RWG) and the upconversion fluorescence emission of rare-earth nanoparticles, we propose to develop an original method for high sensitivity wide-field optical microscopy as well as for realization of an ultra-sensitive sensing technique.
- The 1st topics of this joint-proposal is to develop a novel type wide-field UCFM using a RWG structure as a substrate and UCNPs as bio-markers to observe surface images of bio-specimens. High-contrast and high-resolution UCF images will be obtained.
- The 2nd topics of this joint-project is to develop a label-free, wide-field, RWG-enabled polarimetric optical microscopy.
The project proposes a high-quality and long-term research, which will combine different fields such as nanotechnology, nanophotonics, material science, and nonlinear optics to achieve radically new photonic device and optical instruments.
