    • The present invention provides a wavelength division multiplexing filter that requires lower costs, a smaller size, and a smaller amount of fiber routing operations. According to the present invention, a first module constitutes a first filter. A second module constituting a second filter is produced by connecting together circuits identical in number to a plurality of output ports of the first module, the circuits each comprising a combination of directional couplers and Bragg gratings both formed of silica-based-glass waveguides, the circuits each having a wavelength selection characteristic so as to correspond to each of the output ports. The second module is connected to the first module via an 8-fiber ribbon to simplify the integration and connection of the circuits.
    • 本发明提供了一种波分复用滤波器,其需要较低的成本,较小的尺寸和较少量的光纤路由操作。 根据本发明,第一模块构成第一过滤器。 构成第二滤波器的第二模块通过将数量相同的电路连接在第一模块的多个输出端口来产生,每个电路包括由二氧化硅基玻璃波导形成的定向耦合器和布拉格光栅的组合, 每个具有波长选择特性的电路,以便对应于每个输出端口。 第二个模块通过8光纤带连接到第一个模块,以简化电路的集成和连接。

    • An object of the present invention is to provide a fabrication method for pattern-formed structure having a smooth three-dimensional structure through a fewer processes. To achieve the object, the present invention provides a fabrication method for pattern-formed structure comprising: a dot modulation pattern forming process of binarizing a shape of a targeted three-dimensional structure to form a dot modulation pattern, a writing process of using the dot modulation pattern to write directly by a writer on a photosensitive resin layer formed on a substrate, and a developing process of developing the photosensitive resin layer after the writing to form a resin layer with three-dimensional structure, wherein the writing process is performed by a writing energy supplying method in which writing energy is supplied to the photosensitive resin layer by an area larger than a minimum dot area in the dot modulation pattern.
