我们利用倾斜的少模光纤布拉格光栅（FM-FBG）的光反射实验证明了模式转换。利用1.6度倾斜的FM-FBG实现了从LP01模式到更高对称和非对称模式的模式转换，从LP01到LP11模式的转换效率超过99.5%。分析和讨论了弱倾斜FM-FBG参数对模式转换特性的影响。提出了一种4模x 3波长复用传输的同时模式转换与解复用方案，并基于倾斜fm - fbg的传输光谱分析了模态串扰。该方法在模式和波分复用通信系统中具有潜在的应用前景。(C) 2015美国光学学会
We experimentally demonstrate mode conversion by exploiting optical reflection of tilted few-mode fiber Bragg grating (FM-FBG). Mode conversions from LP01 mode to higher symmetric and asymmetric modes are achieved, and more than 99.5% conversion efficiency from LP01 to LP11 mode is obtained using a 1.6 degrees-tilted FM-FBG. Influences of the weakly tilted FM-FBG parameters on the property of mode conversion is analyzed and discussed. A simultaneous mode conversion and demultiplexing scheme for 4-mode x 3-wavelength multiplexing transmission is proposed and the modal crosstalk is analyzed based on the transmission spectra of the tilted FM-FBGs. The proposed approach shows potential applications in mode and wavelength division multiplexing communication systems. (C) 2015 Optical Society of America
