“…Consequently, SHG is forbidden in centrosymmetric materials and can only appear in the regions of broken symmetry such as surfaces, interfaces, chiral ordering, etc [28]. In general, the number of independent components of the third rank tensor This last component is often referred to as the "chiral" one, since it is characteristic of the absence of mirror symmetry that is associated with chiral systems.…”

Abstract:In optics, chirality is typically associated with circularly polarized light. Here we present a novel way to detect the handedness of chiral materials with linearly polarized light. We performed Second Harmonic Generation (SHG) microscopy on G-shaped planar chiral nanostructures made of gold. The SHG response originates in distinctive hotspots, whose arrangement is dependent of the handedness. These results uncover new directions for studying chirality in artificial materials.

Abstract:While it has been demonstrated that, above its resolution limit, Second Harmonic Generation (SHG) microscopy can map chiral local field enhancements, below that limit, structural defects were found to play a major role. Here we show that, even below the resolution limit, the contributions from chiral local field enhancements to the SHG signal can dominate over those by structural defects. We report highly homogeneous SHG micrographs of star-shaped gold nanostructures, where the SHG circular dichroism effect is clearly visible from virtually every single nanostructure. Most likely, size and geometry determine the dominant contributions to the SHG signal in nanostructured systems. References and links1. J. B.

“…The resonance principle can be found in the roots of many macroscopic real-time 3D visualization techniques with one of the brightest examples being MRI (magnetic resonance imaging), which is exploiting the resonance of a nucleus of atoms absorbing energy from the magnetic field and is often used to image internal organs in medical diagnosis. On the other hand, resonance of light waves is mostly used for investigation of living cells and tissues and provide foundation of techniques such as optical tomography, speckle-interferometry, non-linear optical microscopy or FRET (Lauterborn et al, 2003;Periasamy & Diaspro, 2003;Lakowicz, 2006;Verbiest et al, 2009;Sun et al, 2011). All these technologies take profit from a special capacity of resonance to improve the signal recognition from the studied phenomena while minimizing sample damage.…”
