项目摘要

The purpose of this studies is the development of new connecting technique of optical circuits. By the new technique, the optical axs may automatically coincide with each other. The principle of this method is as follows. The phase-conjugate wave (PCW) is oscillated between two phase-conjugate mirrors included two optical waveguide to be spliced in the optical path. The high connecting efficiency with the phase-conjugate wave is expected even though the existence of the connection imperfections because of the time reversibility of the PCW property. After the generation of the PCW,the light hardening resins among the optical waveguides are hardened by the PCW.As the result, the connection path between two optical waveguides is formed without the alignment manipulation of the optical axs. We call the new method as the "connection technique of the self-alignment type". Our experimental studies reveal the following results.1. The degenerate four wave mixing system was constructed with BaTiO_3 single crystal and 514.5nm wave from Argon ion laser. The phase-conjugate reflection efficiency of 10000% was realized by the propagating light through the fiber as pump beam in the four wave mixing.2. The connection efficiency against the connection imperfection of two fibers measured by the PCW was higher than that by the conventional light wave.3. The light hardening resins were hardened along by the light path radiated from the edge of the fiber.These results encourage realization of our new connecting technique. The automatic formation of the connection path by this method has not confirmed yet, because the sufficient power of PCW and the oscillation of PCW between two phase-conjugate mirrors have not obtained yet. We will continue to study and to resolve these problems.

本研究的目的是开发新的光电路连接技术。通过这种新技术，光轴可以自动重合。这种方法的原理如下。相位共轭波（PCW）在包含两个光波导的两个相位共轭镜之间振荡，在光路中进行拼接。由于PCW特性的时间可逆性，即使存在连接缺陷，也期望与相位共轭波的高连接效率。PCW生成后，光波导之间的光硬化树脂被PCW硬化。这样就形成了两个光波导之间的连接路径，而不需要对光轴进行对齐操作。我们将这种新方法称为“自对准型连接技术”。我们的实验研究揭示了以下结果：用BaTiO_3单晶和氩离子激光514.5nm波长构建了简并四波混频系统。在四波混频中，光以泵浦光束的形式在光纤中传播，实现了10000%的相位共轭反射效率。PCW测量的两根光纤对连接缺陷的连接效率高于传统光波测量的连接效率。光硬化树脂沿光纤边缘辐射的光路硬化。这些结果促进了我们的新连接技术的实现。由于还没有获得足够的PCW功率和两个相位共轭镜之间的PCW振荡，这种方法能否自动形成连接路径还没有得到证实。我们将继续研究和解决这些问题。
