Abstract
Many consider optics and photonics to be the technological revolution of the 21st Century. Nonlinear optics (NLO), whereby light is directly controlled by light, has a wide range of applications in our daily lives. However, current nonlinear optical interactions are generally based on large crystals, which are not compatible with the size requirements of cutting-edge miniaturized systems. Here, I review the latest advances in obtaining efficient nonlinear signals from tailored structures at nanoscale, whose thicknesses are typically a few hundred times less than a human hair.
