摘要	An inventive optical functional device includes: two optical waveguides having mutually different equivalent refractive indices; and a connection through which the two optical waveguides are connected along an optical axis. The two optical waveguides are provided as a first optical waveguide, and a second optical waveguide having an equivalent refractive index lower than that of the first optical waveguide, respectively. The connection, through which the first and second optical waveguides are connected along the optical axis, is formed by selectively enlarging the width of the second optical waveguide, and is allowed to function as a multimode interference waveguide. The connection allows multimode propagation of a light passing through the second optical waveguide, and allows the light to be coupled into the first optical waveguide.
其他摘要	本发明的光学功能器件包括：两个具有相互不同的等效折射率的光波导;以及两个光波导沿光轴连接的连接。提供两个光波导作为第一光波导，和分别具有低于第一光波导的等效折射率的第二光波导。第一和第二光波导沿光轴连接的连接通过选择性地扩大第二光波导的宽度而形成，并且允许用作多模干涉波导。该连接允许穿过第二光波导的光的多模传播，并允许光耦合到第一光波导中。
