Second-harmonic generation in Mie-resonant dielectric nanoparticles made of noncentrosymmetric materials

Kristina Frizyuk, Irina Volkovskaya, Daria Smirnova +2

We develop a multipolar theory of second-harmonic generation (SHG) by dielectric nanoparticles made of noncentrosymmetric materials with bulk quadratic nonlinearity. We specificall…
