    • When the longitudinal central axis line of a first linear wave-guide 2 that receives light is set to be a reference line, open portions of circular arcs of first curved wave-guides 4a, 4b that are coupled to a tapered wave-guide 3 face outward when viewed from the reference line. On the other hand, open portions of circular arcs of second curved wave-guides 5a, 5b that are coupled to the first curved wave-guides 4a, 4b face inward when viewed from the reference line. Furthermore, second linear wave-guides 6a, 6b, which are coupled to the first linear wave-guide through the first and second curved wave-guides, and the reference line X are outwardly coupled to form an angle, which is set to be greater than 0 degree. According to the present invention, there can be provided a branch optical wave-guide that can make its entire length short with polarization property of respective output ports equalized.
    • 当接收光的第一线性波导2的纵向中心轴线被设定为基准线时,第一弯曲波导4a,4b的圆弧的开口部分与锥形波导3面 从参考线观察时向外。 另一方面,当从基准线观察时,耦合到第一弯曲波导4a,4b的第二弯曲波导5a,5b的圆弧的开口部分向内。 此外,通过第一和第二弯曲波导耦合到第一线性波导管的第二线性波导6a和6b以及参考线X被外连接以形成一个角度,其被设定为更大 0度以上。 根据本发明,可以提供一种分支光波导,其可以使其整个长度短,各个输出端口的偏振特性相等。
