Direct near-field optical imaging of UV bowtie nanoantennas.
We report near-field optical imaging of bowtie nanoantennas obtained using a UV near-field scanning optical microscope (NSOM). A strong and highly localized UV intensity profile was observed at the antenna gap due to the localized surface plasmon resonance. The relationship of optical field enhancement and antenna size is discussed based on numerical simulations and NSOM experiments.
