Harmonic Generation in Transparent Conducting Oxides: From Nanolayers to Multilayers and Photonic Crystals Arrangements

Transparent conducting oxides have emerged as important players for nonlinear interactions at the nanoscale thanks to the presence of plasma resonances in the infrared range. Here we focus our attention on second and third harmonic generation from transparent conducting oxides in simple arrangements, like freestanding and Kretschmann configurations, and in more complex planar settings, such as multilayer structures or one-dimensional photonic crystals.
