Abstract
Plasmon nanofocusing has been gaining much attention as a tool to create a nanoscale light source over a broad wavelength range. The nanoscale light source is generated by plasmons propagating on a tapered plasmonic structure toward its apex, which eventually induces a strong light source at the apex in a nanometric volume. It has recently been recognized as a broadband plasmon phenomenon because it is just based on plasmon propagation. We have recently reported the generation of white nanolight source and its application for broadband scattering spectral near-field optical imaging. We will talk more about recent advances that we made using the broadband property of plasmon nanofocusing.
