1.光纤耦合器
光纤型耦合器是把两根或多根光纤排列,用熔融拉锥法制作出来的器件。一个输入的光信号分配给多个输出。
熔融拉锥法就是将两根或两根以上除去涂覆层的光纤以一定的方式靠拢,在高温加热下熔融,同时向两侧拉伸,最终在加热区形成双锥体形式的特殊波导结构,实现传输光功率耦合的一种方法(一般是对同一波长的光功率进行合路或分路,区别于波分复用器)


耦合区域的长度L决定了两根光纤之间的耦合比。在制造过程中,在端口Pin端持续输入光波,然后实时监控每个输出端口的输出功率。当达到设计的耦合比时,全自动的制造过程就会停止拉伸。由此产生的耦合器本质上是一根光纤,但是有两根纤芯,只是两个芯非常接近。这个过程就被称为熔融拉锥(FBT)过程。
2.相关参数计算
对光功率按一定比例进行分配和耦合(光路可逆,数值不可逆)
例50:50耦合器,输入1mw光
输出端口1得到0.5mw光,输出端口2得到0.5mw光
反之输出端口逆向分别输入0.5mw光,原输入端口得不到1mw光
实际得到0.5mw(0.25+0.25)

*光纤耦合器又称光纤分光器,因其原理利用的是光纤之间的耦合,故称光纤耦合器。另外一种常用的分光器通常采用波片式,同样器光路不具备可逆性
