Plasmon Induced Delocalized Second-Harmonic Generation Towards Buried-Interface Spectroscopy
Alan R. Bowman, Sergejs Boroviks, Omer Can Karaman +3
Second-harmonic generation microscopy is a powerful technique capable of probing local crystal symmetries and electric fields at interfaces. However, it often suffers from weak sig…
Crystalline metal flakes: Platforms for advanced plasmonics and hybrid 2D material architectures
Sergejs Boroviks, Siarhei Zavatski, Thorsten Feichtner +4
Crystalline noble metal flakes are emerging as versatile platforms in nanophotonics, enabling a broad range of optical phenomena and applications. Their atomically flat surfaces, h…
Engineering Photoluminescence with Mie Voids
Yuchao Fu, Ilia Lykov, Sergejs Boroviks +5
Spontaneous emission, as a fundamental radiative process and a versatile information carrier, plays a vital role in light-emitting devices, optical information modulation and encry…
Step Function in Momentum Space by a Metagrating
Mahmoud A. A. Abouelatta, Sergejs Boroviks, Olivier J. F. Martin +1
Metasurface research has shown significant potential for controlling the polarization, amplitude, phase and propagation direction of light. Nevertheless, control over the angular r…
Demonstration of a plasmonic nonlinear pseudo-diode
Sergejs Boroviks, Andrei Kiselev, Karim Achouri +1
We demonstrate a nonlinear plasmonic metasurface that exhibits strongly asymmetric second-harmonic generation: nonlinear scattering is efficient upon excitation in one direction an…
Ultimate limit for optical losses in gold, revealed by quantitative near-field microscopy
Yonas Lebsir, Sergejs Boroviks, Martin Thomaschewski +2
We report thorough measurements of surface plasmon polaritons (SPPs) running along nearly perfect air-gold interfaces formed by atomically flat surfaces of chemically synthesized g…
Anisotropic Second Harmonic Generation From Monocrystalline Gold Flakes
Sergejs Boroviks, Torgom Yezekyan, Álvaro Rodríguez Echarri +5
Noble metals with well-defined crystallographic orientation constitute an appealing class of materials for controlling light-matter interactions on the nanoscale. Nonlinear optical…
Interference in edge-scattering from monocrystalline gold flakes
Sergejs Boroviks, Christian Wolff, Jes Linnet +6
We observe strongly dissimilar scattering from two types of edges in hexagonal quasi-monocrystalline gold flakes with thicknesses around 1 micron. We identify as the origin the int…
