Photonic lenses with whispering gallery waves at Janus particles
Journal Title: Opto-Electronic Science - Year 2022, Vol 1, Issue 2
Abstract
We show that electric field on the plane surface of truncated sphere or cylinders (so called Janus particles) have sharp resonances versus the depth of removed segment of a sphere or cylinder. These resonances are related to the excited whispering gallery waves caused by truncation. It is a new mechanism of the field localization. Optimization of this effect for cylinders permits to reach a super resolution in the line thickness, which can be used for contact optical lithography.
