Nonlinear circular dichroism in achiral dielectric nanoparticles

چکیده
We present a theoretical study of circular dichroism in the second-harmonic signal single dielectric nanostructures with different symmetries and noncentrosymmetric materials. show that this effect is defined not only by macroscopic (particle) lattice but also their relative orientation. Using symmetry modal analysis, we provide general very simple formula to determine whether exists chart most significant cases.

All-dielectric metasurface circular dichroism waveplate
We propose and experimentally demonstrate a high efficient circularly polarizing dichroism waveplate (CPDW) using a Si-based all-dielectric 2Dchiral metasurface. We demonstrate that the CPDW exhibits a unique dichroism in that it functions as a transmissive quarter waveplate for one of either left-or right-handed circularly polarized incident lightand a reflective mirror for the opposite polari...
متن کاملHarmonic distortions enhance circular dichroism of dielectric single gyroids.
The departure from strict periodic order in two-phase dielectric materials can offer properties that are otherwise inaccessible to perfectly ordered photonic crystals. Herewith, we investigate the circular dichroism of the single gyroid photonic crystal in the presence of spatial distortions. FDTD simulations and microwave transmission measurements on 3D-printed replicas show that certain harmo...

متن کاملNumerical study of achiral phase-change metamaterials for ultrafast tuning of giant circular conversion dichroism
Control of the polarization of light is highly desirable for detection of material's chirality since biomolecules have vibrational modes in the optical region. Here, we report an ultrafast tuning of pronounced circular conversion dichroism (CCD) in the mid-infrared (M-IR) region, using an achiral phase change metamaterial (PCMM). Our structure consists of an array of Au squares separated from a...
متن کاملFirst enantioseparation and circular dichroism spectra of Au38 clusters protected by achiral ligands
Bestowing chirality to metals is central in fields such as heterogeneous catalysis and modern optics. Although the bulk phase of metals is symmetric, their surfaces can become chiral through adsorption of molecules. Interestingly, even achiral molecules can lead to locally chiral, though globally racemic, surfaces. A similar situation can be obtained for metal particles or clusters. Here we rep...
