| 摘 要： | 提出一种新型的光纤干涉仪 ,它是采用二个 3× 3单模光纤耦合器组成三光纤系统的马赫 -曾德尔 (Mach- Zehnder)干涉仪 ,当干涉仪的三条光纤干涉臂两两之间分别存在长度差Δ L和2Δ L时 ,干涉仪形成了一个波分复用间隔相等的三波分复用器 ,波分复用的波长间隔仅仅取决于ΔL的大小。实验样品的使用波段为 1.55μm,波长复用间隔为 1.6 nm,附加损耗为 0 .6 d B。

| Abstract: | A new type fiber interferometer has been fabricated. It is a Mach-Zehnder Interferometer made of two 3×3 single-mode fiber couplers connected by 3 single-mode fibers. The lengths of these 3 single-mode fiber are L, L+ΔL, and L+2ΔL respectively. This interferometer acts as a 3 channel wavelength-division-multiplexer. The wavelength between two channels is dependent on ΔL only. The experimental sample tested offers 1.6 nm wavelength division spacing and 0.6 dB total insertion loss at 1.5 μm working wavelength. |
