对称结构光纤光栅耦合器及其应用
Symmetric fiber grating coupler and its application
摘要
光纤光栅耦合器(FGC)具有光纤光栅良好的波长选择特性和光纤耦合器的多端口特点,易于实现全光纤的光波分插复用。光纤光栅耦合器主要有4种结构:基于M-Z干涉仪的分离型、基于100%耦合器的非对称型、基于0耦合器的非对称型和基于100%耦合器的对称型。着重介绍对称结构光纤光栅耦合器的结构、工作原理和研究现状。提出了测试方案,并探讨了这种器件在大规模波分复用光纤传感器阵列中的应用。
Abstract
Fiber grating coupler (FGC) has good wavelength selection characteristic of optical fiber grating as well as multiport advantage of fiber coupler. These features make it easy to realize all-fiber optical add/drop multiplex (OADM). Now there are four major types of FGCs: separated structure based on Mach Zehnder interferometer,dissymmetric structure based on 100% coupler,dissymmetric structure based on 0 coupler and symmetric structure based on 1000% coupler. The structure,operation principle and present situation of the symmetric structure FGC are introduced emphatically. The test method for the device is proposed. Furthermore,the application of this device used in large-scale WDM optical fiber sensor arrays was also investigated.
