Due to the subwavelength localization property of surface plasmons, traditional optical microscopy cannot fulfill the requirement of plasmonic characterization at nanoscale. To provide better guidelines for the design of nanophotonic devices, precisely revealing plasmonic properties at nanoscale is needed. Photoemission electron microscopy (PEEM) has been demonstrated as a promising approach to investigate the plasmonic properties of surface plasmons.
The research group of Prof. Hiroaki Misawa from the Research Institute for Electronic Science at Hokkaido University studies on the plasmonic properties by using PEEM. They developed an ultrafast PEEM system, which allows to characterize the near-field properties of surface plasmons in multiple (spatial, spectral, and temporal) domains.
