波长选择开关
摘要：
本发明提供一种波长选择开关，在波长选择开关中，设定为各值满足式（θ2＞2×θ1＋α），因此，在动作时对反射镜的倾斜角进行变更，使一次反射光以接近输出端口的方式移动时，二次反射光以远离输出端口的方式移动。因此，在对反射镜的倾斜角进行变更，使一次反射光与输出端口耦合时，抑制二次反射光与输出端口的耦合。
摘要（英）：

The invention provides a wavelength selective switch. In the wavelength selective switch, all values are set to meet a formula [theta]2 > 2*[theta]1 + alpha, so that a secondary reflected light moves in a manner far away from an output terminal when the wavelength selective switch is operated to change an inclined angle of a reflector so as to make first reflected light move in a manner close to the output terminal. Therefore, when the inclined angle of the reflector is changed to couple the first reflected light with the output terminal, the couple of the secondary reflected light and the output terminal are suppressed.
