Abstract

In scanning near-field optical microscope, the optical resolution is determined by the actual size of the optical nano-antenna at the apex of the tip. In this talk, I will introduce our recent improvements in fabricating the ‘Campanile’ near-field Probe with the gap in a sub-20nm scale size. The near-field optical performance of the probe will be demonstrated through the polarization-resolved transmission measurement and the nano-photoluminescence mapping of the WSe2 monolayer.
