摘要	PURPOSE:To easily obtain an optical filter element whose optical axis can be aligned by arranging the optical filter element in parallel with a semiconductor element and optically coupling them with the same waveguide. CONSTITUTION:When an optical integrated element which is constituted in such a way that a semiconductor laser 200 and optical filter element 300 are arranged in parallel to each other and they are optically coupled with the same waveguide 100 is used, optical axis alignment can be easily executed by oscillating the laser 200. When this element is operated as an optical filter element, no electric current is supplied to the semiconductor element. When no electric current is supplied to the laser, rays of light branched to the laser side of the incident rays of light are absorbed and not transmitted by the activation layer of the laser. On the other hand, of rays of light branched to the filter element side of the incident rays of light, those having a specific wavelength are transmitted in accordance with the transmission characteristic of the filter element. Therefore, the characteristic of this optical integrated element as an optical filter element is not deteriorated even if the semiconductor laser is integrated in this element in parallel with the optical filter element.
其他摘要	目的：通过将光学滤波器元件与半导体元件平行布置并将它们与相同的波导光学耦合，以便容易地获得其光轴可以对准的光学滤波器元件。组成：当使用以半导体激光器200和光学滤波器元件300彼此平行排列并且它们与同一波导管100光学耦合的方式构成的光学集成元件时，可以容易地进行光轴对准当该元件作为光学滤波器元件工作时，没有电流供给半导体元件。当没有电流供给激光器时，分支到入射光线的激光侧的光线被吸收而不被激光器的激活层透射。另一方面，在入射光线的滤光器元件侧分支的光线中，具有特定波长的光线根据滤光器元件的透射特性传输。因此，即使半导体激光器与光学滤波器元件并联地集成在该元件中，该光学集成元件作为光学滤波器元件的特性也不会恶化。
