摘要

本文从理论和实验两方面报道了三维准相位匹配（QPM）的级联三次谐波产生。介绍了一种用于高效THG的周期三维非线性光子晶体（NPC）设计的系统演示。利用全光极化技术在Sr0.61Ba0.39NbO3晶体上制备了包含两个亚段的非线性光子结构。第一部分是用于高效共线二次谐波产生（SHG）的1D χ(2)光栅，而第二部分是设计用于THG的3D NPC。有效的共线和非共线TH波均可实现，SHG和THG的最大转换效率分别为3.1%和8.4 × 10-3%。我们的发现加深了对三维npc级联THG的理解，并推动了通过高维QPM工艺产生多通道高谐波的发展。

Multi-channel third-harmonic generation via period 3D nonlinear photonic crystals

We report the cascaded third-harmonic generation (THG) via 3D quasi-phase matching (QPM) both theoretically and experimentally. A systematic demonstration of periodic 3D nonlinear photonic crystal (NPC) design for efficient THG is presented. A nonlinear photonic structure contains two subsections was fabricated by all-optical poling technique in an Sr_0.61Ba_0.39NbO₃ crystal. The first segment is a 1D χ⁽²⁾ grating for efficient collinear second-harmonic generation (SHG), while the second is a designed 3D NPC for THG. Effective collinear and non-collinear TH waves were realized, achieving maximum conversion efficiencies of 3.1 % for SHG and 8.4 × 10^-3% for THG. Our findings deepen the understanding of cascaded THG in 3D NPCs and advance the development of multi-channel high-harmonic generation via high-dimensional QPM processes.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
