Second harmonic generation from GaAs-Au subwavelength relief gratings

open access: yesResults in Physics, 2022
We study numerically the second-harmonic generation (SHG) from subwavelength GaAs relief gratings with and without Au nano-stripes on the bottom of grating troughs.

Second-Harmonic-Generation-Active Oxyhalides: CuSb2O3X (X = Cl, Br)

open access: yes, 2021
Metal oxyhalides have attracted broad interest recently because of their diverse structures and versatile properties. Here, two oxyhalides, CuSb2O3Cl (1) and CuSb2O3Br (2), were studied by focusing on their nonlinear-optical properties.

Second Harmonic Generation from Phase-Engineered Metasurfaces of Nanoprisms

open access: yesMicromachines, 2020
Metasurfaces of gold (Au) nanoparticles on a SiO2-Si substrate were fabricated for the enhancement of second harmonic generation (SHG) using electron beam lithography and lift-off.

Second harmonic generation from an ITO nanolayer: experiment versus theory [PDF]

open access: yes, 2020
We report a comparative experimental and theoretical study of second harmonic generation from a 20nm-thick indium tin oxide nanolayer in the proximity of the epsilon-near-zero condition.

Second harmonic generation from the `centrosymmetric' crystals

open access: yesIUCrJ, 2015
Second harmonic generation (SHG) is a well known non-linear optical phenomena which can be observed only in non-centrosymmetric crystals due to non-zero hyperpolarizability.

Vertical Second Harmonic Generation in Asymmetric Dielectric Nanoantennas

open access: yesIEEE Photonics Journal, 2020
High-permittivity III–V semiconductor nanocavities have shown huge potential for enhanced nonlinear light–matter interactions at the nanoscale. In particular, Second Harmonic (SH) generation in AlGaAs nanoantennas can be extremely efficient;

Label-free 3D visualization of cellular and tissue structures in intact muscle with second and third harmonic generation microscopy. [PDF]

open access: yes, 2011
Second and Third Harmonic Generation (SHG and THG) microscopy is based on optical effects which are induced by specific inherent physical properties of a specimen.

Resonant second harmonic generation in random dielectric structures [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2006
We show that resonant second harmonic generation can be obtained in random dielectric structures. The scheme is based on internal resonances due to the optical counterpart of Anderson localization.
