Detection of Hybrid Optical Anapoles in Dielectric Microspheres
Advanced Optical Materials, Volume 13, Issue 27, September 23, 2025.In this work, hybrid optical anapoles are detected in dielectric microspehers using dual detection optical spectroscopy. The results show that the excitation of TiO2 microspheres under tightly focused Gaussian Beam illumination leads to the appearence of scattering minima in both the forward and backward directions within specific wavelength ranges ...

Theory for bowtie plasmonic nanolasers
Optics Express, 2008 We develop a fundamental formulation for electrically-pumped plasmonic semiconductor nanolasers based on a metallic bowtie structure. Because of the negative dielectric constant of the metal at optical frequencies, the effective modal volume of the plasmonic mode can be compressed to the nanometer scale.
