Optical Third Harmonic Generation Using Nickel Nanostructure-Covered Microcube Structures

Optical Third Harmonic Generation Using Nickel Nanostructure-Covered Microcube Structures

We investigated the optical third harmonic generation (THG) signal from nanostructure-covered microcubes on Ni. We found that the hierarchical structures greatly change the third-order optical nonlinearity of the metallic surface. While the symmetry and lightning rod (LR) effects on microstructures...
