Photonic Lenses with Whispering Gallery Waves at Janus Particles
Igor V. Minin, Oleg V. Minin, Yinghui Cao +3
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…
Specular-reflection photonic hook generation under oblique illumination of a super-contrast dielectric microparticle
Yu. E. Geints, A. A. Zemlyanov, I. V. Minin +1
The possibility of overcoming the critical condition for localized photonic nanojet upon plane optical wave diffraction at mesoscale dielectric particle, which is commonly known as…
Super-enhancement focusing of Teflon sphere
Liyang Yue, Zengbo Wang, Bing Yan +5
A Teflon (Polytetrafluoroethylene, PTFE) sphere can be used as a focusing lens in the applications of imaging and sensing due to its low-loss property in the terahertz (THz) band.…
Concept of photonic hook scalpel generated by shaped fiber tip with asymmetric radiation
Igor V. Minin, Oleg V. Minin, Yan-Yu Liu +1
Structured light have made deep impacts on modern biotechnology and clinical practice, with numerous optical systems and lasers currently being used in medicine to treat disease. W…
Experimental verification of a plasmonic hook in a dielectric Janus particle
Igor V. Minin, Oleg V. Minin, Igor A. Glinskiy +5
We report on a very first experimental observation of a new curved plasmonic beam, a plasmonic hook (PH), for surface plasmon-polariton (SPP) waves. We demonstrate that the SPP PH…
Overcoming optical contrast limit of mesoscale light focusing by means of retrograde-reflection photonic nanojet
Yury E. Geints, Alexander A. Zemlyanov, Igor V. Minin +1
The physical origin of subwavelength photonic nanojet in retrograde-reflection mode (retro-PNJ) is theoretically considered. This specific type of photonic nanojet emerges upon seq…
