摘要
利用石墨烯独特的吸收特性以及双芯光纤两芯之间的耦合作用,提出并设计了一种基于石墨烯的D型双芯光纤(DTCF)调制器的结构,该结构结合了吸收调制和耦合调制的优势。仿真验证了结构的调制可行性,基于有限元法数值模拟分析了调制器传输模式、两纤芯半径、纤芯距、石墨烯层数、过渡层材料对调制器性能的影响,并通过性能优化最终实现了调制带宽为8.557 GHz、消光比为67.64 dB、半波电压为1.763 V、调制深度为98.75%、插入损耗为1.4 dB、调制器长度为3.07 mm的高性能调制器。
Abstract
In this study, we propose and design the structure of a graphene-based D-shape twin-core fiber (DTCF) modulator by utilizing the unique absorption characteristics of graphene and the coupling between two cores, which integrates the advantages of absorption modulation and coupling modulation. Further, the modulation feasibility of this structure can be verified using numerical simulation. Subsequently, the effects of the transmission mode, two core radius, twin-core distance, number of graphene layers, and transition layer materials of the modulator on the performances are analyzed based on the finite element method. Finally, a high-performance modulator with a modulation bandwidth of 8.557 GHz, an extinction ratio of 67.64 dB, a half-wave voltage of 1.763 V, a modulation depth of 98.75%, an insertion loss of 1.4 dB, and a modulator length of 3.07 mm can be achieved through optimization.
