Lasing action in active dielectric nanoantenna arrays
Son Tung Ha, Yuan Hsing Fu, Naresh Kumar Emani +4
Directional lasing, with a low threshold and high quality factor, in active dielectric nanoantenna arrays is demonstrated. This is achieved through a leaky resonance excited in cou…
A Metalens with Near-Unity Numerical Aperture
Ramon Paniagua-Dominguez, Ye Feng Yu, Egor Khaidarov +8
The numerical aperture (NA) of a lens determines its ability to focus light and its resolving capability. Having a large NA is a very desirable quality for applications requiring s…
Seeing the unseen: observation of an anapole with dielectric nanoparticles
Andrey E. Miroshnichenko, Andrey B. Evlyukhin, Ye Feng Yu +6
Nonradiating current configurations attract attention of physicists for many years as possible models of stable atoms in the field theories. One intriguing example of such a nonrad…
