项目摘要

The purpose of this research project is to explore the new academic frontier which we call Photonic Crystal Engineering and to develop various device applications using the obtained concepts. The followings are the main results of this project.I. High Q nanocavities ; We have developed a cubic-wavelength-size nanocavity with a Q factor of 2.5 million. This Q factor is more than 1000 times the initial value at the point when we started the project. The nanocavity amazed all the researchers around the world due to its high performance, and is now called as Noda's cavity to be utilized in various areas. The two papers describing the nanocavities were awarded from Thomson ISI as one of the highest citation ratio articles in science and material area. Moreover, one of the two papers is selected as one of the 10 best papers when Nature Materials celebrated the 5 years anniversary.II. In-plane heterostructure : The concept of in-plane heterostructure proposed in this project enables multi-wav … More elength operation of photonic crystal devices while maintaining the best coupling between line and point defects. This concept constitutes a fundamental technique for the design of nano-photonic devices and has great impact on all the researchers in this area around the world. Moreover, a variety of techniques stemmed from this concept are now widely utilized to create high performance photonic components.III. Dynamic control : So far, researches on photonic crystals were mainly focused on the static characteristics. It is especially important that the concept of dynamic control of the characteristic of photonic crystals was proposed and demonstrated in this project. This concept will be inevitable for the future photon manipulation technologies such as stopping of light, optical quantum information technologies, and etc. The result was written up by Nature Materials in the section of News & Views.IV. Device applications : Novel photonic crystal based add-drop devices that can process 16 wavelength channels and in-plane channel add-drop devices have been developed for the first time. Furthermore, the methods to obtain a flat-top response and a polarization free operation have been proposed and demonstrated.To summarize, we have succeeded in achieving various world leading results and deepening the Photonic Crystal Engineering. One of these results was published in Science, another in Nature, the other two in Nature Materials and another in Nature Photonics. These results were attracted much attention not only within Japan, but also around the world. Less

本研究项目的目的是探索我们称为光子晶体工程的新的学术前沿，并利用所获得的概念开发各种器件应用。本项目的主要成果如下：1.高Q纳米腔；我们研制出了Q因子为250万的立方波长大小的纳米腔。这个Q系数是我们开始项目时的初始值的1000多倍。由于其高性能，纳米腔令世界各地的研究人员惊叹不已，现在被称为野田腔，将在各个领域得到利用。这两篇描述纳米空间的论文被汤姆森ISI评为科学和材料领域被引用率最高的文章之一。此外，这两篇论文中的一篇被选为《自然材料》成立五周年十大最佳论文之一。II.面内异质结构：本项目提出的面内异质结构的概念使多波…成为可能更长的光子晶体器件运行长度，同时保持线和点缺陷之间的最佳耦合。这一概念构成了设计纳米光子器件的基本技术，对全世界这一领域的所有研究人员都产生了巨大的影响。此外，源于这一概念的各种技术现在被广泛用于制造高性能的光子元件。III.动态控制：到目前为止，对光子晶体的研究主要集中在静态特性上。尤其重要的是，本项目提出并论证了动态控制光子晶体特性的概念。这一概念将是未来光子操纵技术如光阻止、光量子信息技术等不可避免的。这一结果由自然材料在新闻与观点部分撰写。IV.器件应用：首次开发了可处理16个波长通道的新型光子晶体分插器件和平面通道分插器件。此外，还提出并演示了获得平顶响应和无偏振操作的方法。综上所述，我们成功地取得了各种世界领先的成果，深化了光子晶体工程。其中一项研究结果发表在《科学》杂志上，另一篇发表在《自然》杂志上，另外两篇发表在《自然材料》杂志上，另一篇发表在《自然光子学》杂志上。这些结果不仅在日本国内引起了极大的关注，而且在世界各地也引起了极大的关注。较少
