Nanophotonics Lab

The Nanophotonics Lab at PSU studies photonic processes in nanostructures. We use ultrafast photoemission microscopy to observe optical processes on the nanoscale with femtosecond time resolution. Our home-built microscope can directly visualize light propagation in solids or at their surfaces. We study processes like energy transfer, energy conversion, electron emission, surface plasmon generation etc. We apply the gained knowledge to the design of new devices. Novel solar cells, light emitting diodes, random lasers and plasmonic energy converters are examples for our work.
