摘要

我们预测，极窄的光束(几个波长的宽度)可以用于二次非线性光子晶体中有效的二次谐波产生，同时调谐到亚衍射(自准直)制度，基本和二次谐波，波。本文分别用谐波展开法和时域有限差分积分法对这一思想进行了解析和数值证明。

Second harmonic generation of narrow beams in subdiffractive photonic crystals

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.
