| 摘 要： | 提出一种设计多路分光器分光比的新方法--分解组合法.将多路分光器视为光二分路器的各种组合,分解后,引入等效光纤长度的新概念,将分光损耗对等折算为一定长度的光纤损耗,再利用光二分路器分光比的简便设计方法,巧妙地设计出多路分光器的各路分光比.

| Abstract: | A new method to design optical divide ratio of multi-output optical distributor is proposed, which is called analysissynthesis method. Multi-output optical distributor is regarded as different combination of two-output optical distributor, and the new notion of equivalent optical fiber length is introduced. The optical divide loss is converted equivalently into the optical fiber loss of a certain length. Each optical divide ratio of a multi-output optical distributor is designed by simple means of designing optical divide ratio of two-output optical distributor handily. |
