项目摘要

The objective of this research is development of self-induced optical pulse generation using recursive photochromatic process. In general, a living thing is considered to be a kind of the optimized system. Applying it in engineering effectively, development of a novel and eco-friendly functional material is expectable. In this project, the optical receptiveness protein which exists also in our eyes is taken up. Optical receptiveness protein changes the form by the difference in the color of light (isomerization). It returns to the form of a basis through the process of some isomerization. Focusing on this recursive optical isomerization of the optical receptiveness protein, the phenomenon under existence of the multi-caolor light as environment is examined paying attention to its various behavior.For the purpose, we have proposed the novel method for modulation of light using the recursive photochromatic process of optical receptiveness protein. To verify the proposed method, we adopted "bacteriorhodopsin" as an optical receptiveness protein. As a result of experimental verification, we confirmed that the proposed method function successfully in bacteriorhodopsin. To make a full use of various properties of bacteriorhodopsin in this method, we delved into the this recursive optical isomerization of bacteriorhodopsin from ultra-fast regime to slow one.From the results of this research, we can obtain the important knowledge, with which the proposed method would become a new approach for application of bio-materials (ex. optical pulse generation).

本研究的目的是发展利用递归光致变色过程产生自感生光脉冲。一般来说，生物被认为是一种优化的系统。将其有效地应用于工程中，开发出一种新型的、环保的功能材料是可望的。在这个项目中，也存在于我们眼睛中的光学感受性蛋白被利用起来。光学感受性蛋白通过光的不同颜色改变形式(异构化)。它通过某种异构化过程返回到碱的形式。针对光学感受性蛋白的这种递归光学异构化现象，研究了多色光作为环境存在的现象，并对其各种行为进行了研究，提出了利用光学感受性蛋白质的递归光致变色过程对光进行调制的新方法。为了验证所提出的方法，我们采用“细菌视紫红质”作为光学感受性蛋白。实验验证的结果表明，该方法在细菌视紫红质中的作用是成功的。为了充分利用细菌视紫红质的各种性质，我们深入研究了细菌视紫红质从超快到慢的递归光学异构化。从本研究的结果中，我们可以获得重要的知识，该方法将成为生物材料应用的新途径(例如。光脉冲产生)。
