Year 2004 : Novel pumping system for multi-layered waveguide laser, it termed as Quasi-End-Firing(QEF)' was investigated. Firstly, simulation for designing was programmed and performed. Secondary, we fabricated and evaluated the multiple-layered DFB dye lasers, and demonstrated that the system works well. It requires the multiple-layer spin coating technique with a fine-tuning of refractive indices of the layers.Furthermore, very high conversion efficiency was demonstrated from multiple-layered DFB lasers fabricated with similar processing technique. It has DFB layer without dye and active lay with dye and scattering compounds. In addition, new dye-compound for EL-device was also studied for DFB laser.Year 2005 : The Thermo-optical (TO) effects on the film lasers was studied. As a first step, introducing heater electrode (Al) on the DFB dye laser, and it demonstrated that the lasing wavelength could be switched by applying heating current on the electrode. The numerical analysis was also performed to support the designing. On the other hand, newly DFB fabrication with 244nm laser was studied to improve Bragg reflection of the DFB dye lasers. In addition, as the preliminary experiment for newly fabrication process of "pen drawing", the integration of DFB laser and microflowcytometry chip was developed.Year 2006 : The integration of QEF and TO on DFB film dye laser was mainly studied. However, this complicated DFB dye laser system shows poor process yield, although the improvement of DFB fabrication process was executed on 2005. On the other hand, the pen-drawing processing has developed as a useful technique. The integration of DFB laser and microflowcytometry chip was demonstrated, and its optimization for LIF spectroscopy was done.So, after this research term, we continue to study about TO-QEF DFB laser but using pen-drawing technique. We expect that this new technique improve process wield and obtain better results.

2004年：研究了一种用于多层波导激光器的新型泵浦系统--准端射(QEF)。首先，编制了设计仿真程序并进行了仿真。其次，我们制作了多层DFB染料激光器，并对其进行了测试，结果表明该系统工作良好。这就要求采用多层旋涂技术，微调各层的折射率，并且用类似的工艺制作的多层DFB激光器具有很高的转换效率。它有不含染料的DFB层和含有染料和散射化合物的活性层。此外，还研究了用于电致发光器件的新型染料化合物，用于DFB激光器。2005年：研究了薄膜激光器的热光效应。作为第一步，在DFB染料激光器上引入加热电极(Al)，证明了通过在电极上施加加热电流可以切换激光波长。并进行了数值分析，为设计提供了支持。另一方面，为了改善染料激光器的布拉格反射，研究了用244 nm激光制作DFB的新方法。此外，还开展了DFB激光器与微流控芯片集成的初步实验。2006年：主要研究了DFB薄膜染料激光器上QEF和TO的集成。然而，这种复杂的DFB染料激光系统虽然在2005年进行了DFB制造工艺的改进，但工艺成品率较低。另一方面，笔画处理已经发展成为一种有用的技术。论证了DFB激光器与微流控芯片的集成，并对其在激光诱导荧光光谱中的应用进行了优化，因此，在本研究期满后，我们继续对TO-QEF DFB激光器进行了研究，但采用了画笔技术。我们期待这项新技术能够改善工艺应用，并取得更好的效果。
