Abstract

This work presents a new approach for the design of an FMF with a Gaussian core and a trench in the cladding. For the proposed few-mode fibre (FMF), Fused Silica (SiO2) is considered as a host-material, whereas Germanium Oxide(GeO2) and Fluorine(F)are taken as the dopant for large data transmission. The mole percentages of the dopant material along with the fibre profile parameters are varied to achieve 10 linearly polarized (LP) modes through the proposed FMF. The proposed FMF structure is tested and verified through simulated experiments. The results indicate the proposed FMF structure with the mole percentage 11.5% of GeO2, 2% of F, and the normalized full-width-half-maximum (FWHM) of the core in the range of 4 to 10 supports 10 LP modes in the order of LP01, LP11, LP21, LP02, LP31, LP12, LP41, LP22, LP03, and LP51. The effective index difference (Δneff) between the adjacent LP modes is maintained greater than 1 × 10 3 and a weakly coupled 10x10 Gbps SDM transmission link is established through intensity-modulation and direct-detection (IM/DD) using the proposed Gaussian core-FMF. The link performance is analysed, verified and an acceptable bit-error-rate (BER) of 10−20 is achieved over 50 km without amplifiers.

二氧化硅掺杂GeO2和F材料在SDM通信中的快速光子介质结构
本文提出了一种设计具有高斯芯和包层沟槽的FMF的新方法。对于所提出的少模光纤(FMF),熔融二氧化硅(SiO2)被认为是主材料,而氧化锗(GeO2)和氟(F)被认为是大数据传输的掺杂剂。通过改变掺杂材料的摩尔百分比以及光纤的轮廓参数,通过所提出的FMF实现了10种线极化模式。通过仿真实验对所提出的FMF结构进行了验证。结果表明,所提出的FMF结构中,GeO2的摩尔百分比为11.5%,F的摩尔百分比为2%,核心的归一化全宽半最大值(FWHM)范围为4 ~ 10,支持LP01、LP11、LP21、LP02、LP31、lpp12、LP41、LP22、LP03、LP51等10种LP模式。相邻LP模式之间的有效指数差(Δneff)保持大于1 × 10−3,并通过使用所提出的高斯核心- fmf的强度调制和直接检测(IM/DD)建立弱耦合的10x10 Gbps SDM传输链路。对链路性能进行了分析和验证,在没有放大器的情况下,在50公里内实现了10 - 20的可接受误码率(BER)。
