Abstract

We predict, that extremely narrow beams (of the width of few wavelengths) can be used for an efficient second harmonic generation in quadratic-nonlinear photonic crystals, tuned to the subdiffractive (self-collimating) regime simultaneously for the both, fundamental and the second harmonics, waves. We prove the idea analytically, by harmonic expansion technique, and numerically, by finite difference time domain (FDTD) integration.
