光纤线性偏振模式组合对模分复用系统的影响研究
Research on the Influence of Fiber Linear Polarized Mode Combination on Mode Division Multiplexing System
摘要
Abstract
A research has been carried out on the influence of six four-mode combinations of seven fiber linear-polarization(LP)modes on the mode division multiplexing system in the multi-mode fiber with a core diameter of 50 μm.The seven-LP modes are composed of three reported low-order modes(LP01,LP11,LP21)and four modes(LP02,LP12,LP13,LP14)with significant differences in propagation constants(β).Six different four-mode combinations are selected according to the pattern spot shape and mode coupling characteristics,followed by a simulation test on the Optisystem platform.The results show that with short distance transmission performed in modular division multiplexing,the mode combination of LP01,LP11b,LP12a and LP21b is characterized with the highest Q factor and the optimal eye diagram effect,indicating that this mode combination achieves the best transmission effect.关键词
