Self-transparency and Localization in Gratings with Quadratic Nonlinearityy is commonly employed to achieve phase-matching of frequency conversion process, by means of so called quasi-phase-matching (QPM) techniques , recently extended in planar (2D) geometry . On the other hand also periodic variations of linear properties over submicron scale has been introduc改正 发表于 2025-3-31 08:40:38
