摘要： An optical waveguide type optical terminator forms an optical waveguide structure including at least an optical absorption core (103) which is formed on a clad layer (102) and includes a portion composed of silicon in which an impurity of 1019 cm−3 or more is doped, and is used by being optically connected in series with an optical waveguide including a core (105) composed of silicon. The optical absorption core (103) is sufficient provided that, at least, an impurity of around 1019 cm−3 is doped therein. For example, its impurity concentration is sufficient provided that it falls within a range of 1019-1020 cm−3. The existence of this impurity causes absorption of light in the optical absorption core (103).

摘要： A high-order mode filter includes a slab region, a band-shaped projection elongated in an optical waveguide direction, a first optical waveguide including a disturbance element and a second optical waveguide. The disturbance element is formed by doping impurities into the slab region, thus indicating a lower refractive index than the slab region. Both the first optical waveguide and the second optical waveguide are alternately arranged. The first optical waveguide may include a disturbance element positioned close to the projection, while the second optical waveguide may include a disturbance element distanced from the projection in the slab region. The high-order mode filter causes a large high-order mode loss due to interference between a removable high-order mode and an intentional high-order mode at the connecting face between the first optical waveguide and the second optical waveguide, thus reducing reflected light and stray light.

摘要翻译： 高阶模式滤波器包括平板区域，在光波导方向上延伸的带状突起，包括扰动元件的第一光波导和第二光波导。 扰乱元件是通过将杂质掺杂到板坯区域中形成的，因此表示比板坯区域更低的折射率。 第一光波导和第二光波导都交替布置。 第一光波导可以包括靠近突起定位的扰动元件，而第二光波导可以包括远离板坯区域中的突起的扰动元件。 高阶模式滤波器由于第一光波导和第二光波导之间的连接面处的可移除高阶模式和有意高阶模式之间的干涉而导致大的高阶模损耗，从而减少了反射光 和杂散光。
