Welcome to the Nanophotonics Laboratory at the 精品SM在线影片. 

We study the fundamental mechanisms of light-matter interaction, engineer them in photonic structures and develop novel photonic devices based on them. Examples of photonic structures include plasmonic nanostructures, photonic crystals, metamaterials and metasurfaces and high-Q resonators. We conduct extensive theoretical modeling studies, synthesis and fabrication of nanostructures and spectroscopy and microscopy to demonstrate novel optical phenomena. Targeted applications include nonlinear and quantum optical devices, energy harvesting devices, biomedical imaging and nano-medicine approach for cancer treatment.
