Local Field Asymmetry Drives Second-Harmonic Generation in Noncentrosymmetric Nanodimers
Brian K. Canfield,Hannu Husu,Janne Laukkanen,Benfeng Bai,Markku Kuittinen,Jari Turunen,Martti Kauranen +6 more
TL;DR: It is demonstrated that second-harmonic generation (SHG) from arrays of non-centrosymmetric T-shaped gold nanodimers with a nanogap arises from asymmetry in the local fundamental field distribution and is not related strictly to Nanogap size.
Journal ArticleDOI
Metamaterials with Tailored Nonlinear Optical Response
Hannu Husu,Roope Siikanen,Jouni Mäkitalo,Joonas Lehtolahti,Janne Laukkanen,Markku Kuittinen,Martti Kauranen +6 more
TL;DR: It is demonstrated that the second-order nonlinear optical response of noncentrosymmetric metal nanoparticles (metamolecules) can be efficiently controlled by their mutual ordering in an array, opening new ways for tailoring the nonlinear responses of metamaterials and their tensorial properties.
Journal ArticleDOI
Enhancement of Second-Harmonic Generation from Metal Nanoparticles by Passive Elements
Robert Czaplicki,Hannu Husu,Roope Siikanen,Jouni Mäkitalo,Martti Kauranen,Janne Laukkanen,Joonas Lehtolahti,Markku Kuittinen +7 more
TL;DR: This work prepares arrays of gold nanoparticles that include both noncentrosymmetric particles with a second-order nonlinear optical response and passive particles with no second- order response, providing a completely new concept for optimizing the nonlinear responses of metamaterials.
Journal ArticleDOI
Second-harmonic generation from metal nanoparticles: resonance enhancement versus particle geometry.
Robert Czaplicki,Jouni Mäkitalo,Roope Siikanen,Hannu Husu,Joonas Lehtolahti,Markku Kuittinen,Martti Kauranen +6 more
TL;DR: It is demonstrated that optical second-harmonic generation from arrays of noncentrosymmetric gold nanoparticles depends essentially on particle geometry, and numerical simulations for both linear and second-order responses display unprecedented agreement with measurements.
Journal ArticleDOI
Refractive index and extinction coefficient dependence of thin Al and Ir films on deposition technique and thickness.
TL;DR: The optical properties of thin metallic films depend on the thickness of the film as well as on the deposition technique, and the refractive index and the extinction coefficient are defined using ellipsometry.
