Abstract Background Surgical resection plays a critical role in the curative therapy of patients with gallbladder cancer. However, extended resection for locally advanced gallbladder cancer is a controversial procedure because of the high operative m

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. Triangular Au nanoprisms which are non-centro-symmetric and support s

We present an augmentation of Surface Plasmon (SP)-enhanced second harmonic generation (SHG) due to interference field enhancement in Au nanoprisms (AuNPs) on SiO2-coated Si substrates. The SiO2 spacer contributed for the optical interference and inc

Second-order nonlinear optics was studied about noncollinearly arranged dimeric Au nanorods. The efficient SHG conversions were attributed to noncentro-symmetrically distributed, intense near-fields at nanogap. The roles of the asymmetry on the nonli

The fabrication of ultra-violet (UV) second-harmonic generation (SHG) (UV-SHG) devices requires GaN quasi-phase matching (GaN-QPM) crystals with periodically arranged polar GaN. For fabricating GaN-QPM crystals, the double polarity selective area gro

The intense and confined optical fields due to surface plasmons (SP’s) are useful as ultrasmall light sources for nonlinear optics (NLO) in sub-diffraction spaces. In general, the NLO susceptibilities are closely associated with the geometry of the
