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

该研究项目的目的是探索我们称之为光子水晶工程的新学术前沿，并使用获得的概念开发各种设备应用。以下是该项目的主要结果。高Q纳米腔；我们已经开发了一种立方波长纳米腔，Q系数为250万。该Q因子在开始项目时的初始值是初始值的1000倍以上。纳米腔由于其高性能而使世界各地的所有研究人员都惊讶，现在被称为Noda的腔，可在各个领域使用。描述纳米腔的两篇论文是从汤姆森·伊西（Thomson ISI）授予的，是科学和材料领域中最高的引文比率之一。此外，当大自然材料庆祝5周年纪念日时，这两篇论文之一被选为10篇最佳论文之一。平面异质结构：该项目中提出的平面异质结构的概念使多波动……光子晶体设备的更有效的操作，同时保持线路和点缺陷之间的最佳耦合。这个概念构成了纳米光子设备设计的基本技术，并对世界各地的所有研究人员都产生了巨大影响。此外，现在源于该概念的各种技术现在被广泛用于创建高性能光子组件。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征上。在该项目中提出并证明了对光子晶体特征的动态控制概念尤其重要。对于未来的光子操纵技术，例如停止光，光学量子信息技术等。结果是不可避免的。结果是在News＆Views.iv部分由Natural Materials编写的。设备应用：首次开发了可以处理16个波长通道和平面通道的附加电源设备的新型基于光子晶体的附加电源设备。此外，已经提出并证明了获得扁平响应和无极化操作的方法。总而言之，我们成功地实现了各种世界领先的结果并加深了光子晶体工程。其中一个结果发表在科学中，另一种是自然材料中的另一种结果，另一种是自然光子学。这些结果不仅在日本，而且在世界范围内吸引了很多关注。较少的
