Journal ArticleDOI
Edge States and Topological Phase Transitions in Chains of Dielectric Nanoparticles
Sergey Kruk,Aleksei Slobozhanyuk,Aleksei Slobozhanyuk,Denitza Denkova,Alexander N. Poddubny,Alexander N. Poddubny,Ivan I. Kravchenko,Andrey E. Miroshnichenko,Dragomir N. Neshev,Yuri S. Kivshar +9 more
TL;DR: Polymeric chains of subwavelength silicon nanodisks are studied and it is demonstrated that these chains can support two types of topological edge modes based on magnetic and electric Mie resonances, and their topological properties are fully dictated by the spatial arrangement of the nanoparticles in the chain.
Journal ArticleDOI
Mapping magnetic near-field distributions of plasmonic nanoantennas.
Denitza Denkova,Niels Verellen,Alejandro Silhanek,Ventsislav K. Valev,Pol Van Dorpe,Victor Moshchalkov +5 more
TL;DR: By means of full-field simulations it is demonstrated how the coupling of the hollow-pyramid aperture probe to the nanoantenna induces an effective magnetic dipole which efficiently excites surface plasmon resonances only at lateral magnetic field maxima.
Journal ArticleDOI
Plasmon-Enhanced Sub-Wavelength Laser Ablation: Plasmonic Nanojets
Ventsislav K. Valev,Denitza Denkova,Xuezhi Zheng,Arseniy I. Kuznetsov,Carsten Reinhardt,Boris N. Chichkov,Gichka G. Tsutsumanova,Edward J. Osley,Veselin Petkov,Ben De Clercq,Alejandro Silhanek,Yogesh Jeyaram,Vladimir Volskiy,Paul A. Warburton,Guy A. E. Vandenbosch,Stoyan C. Russev,Oleg A. Aktsipetrov,Marcel Ameloot,Victor Moshchalkov,Thierry Verbiest +19 more
TL;DR: In response to the incident light's electric field, the electron density oscillates in the plasmonic hotspots producing an electric current, and a nanojet and nanosphere ejection can then be observed precisely from the plasmonic hotspots.
Journal ArticleDOI
Mode parity-controlled Fano-and Lorentz-like line shapes arising in plasmonic nanorods
Niels Verellen,F. López-Tejeira,Ramón Paniagua-Domínguez,Dries Vercruysse,Denitza Denkova,Liesbet Lagae,Pol Van Dorpe,Victor Moshchalkov,José A. Sánchez-Gil +8 more
TL;DR: The experimental observation of spectral lines of distinctly different shapes in the optical extinction cross-section of metallic nanorod antennas under near-normal plane wave illumination is presented, offering a perspective and theoretical framework for operating these antennas at higher-order modes.
Journal ArticleDOI
3D sub-diffraction imaging in a conventional confocal configuration by exploiting super-linear emitters.
Denitza Denkova,Martin Ploschner,Martin Ploschner,Minakshi Das,Lindsay M. Parker,Xianlin Zheng,Yiqing Lu,Antony Orth,Nicolle H. Packer,Nicolle H. Packer,James A. Piper +10 more
TL;DR: A conceptually different super-resolution approach which circumvents limitations and enables 3D sub-diffraction imaging on conventional confocal microscopes and relies on markers with super-linear dependence of the emission on the excitation power.
