设计了褶皱石墨烯波导结构激发表面等离子体激元,通过设计周期阵列结构实现了表面等离子体激元传播损耗的补偿.理论分析了周期阵列结构的表面等离子体激元传播模型和补偿损耗的方式,结果表明褶皱衍射激发表面等离子体激元波导不仅能够激发表面等离子体激元,还能利用表面等离子体激元波矢关系实现器件参数控制,周期阵列增益全程补偿损耗的方式可以显著增加表面等离子体激元的传播距离.数值分析结果进一步表明：该结构具备了保持亚波长尺寸的强局域化优势;周期阵列增益全程补偿可以显著提高纳米腔中的电场强度,降低传输损耗;波导结构的粒子反转水平较高,自发辐射噪声的扰动较低.设计的石墨烯波导器件可以为微纳光学集成、光子传感和测量等领域提供理想的亚波长光子器件.

英文摘要：

The folds graphene waveguide excited Surface Plasmon Polaritons（SPPs）was designed and full compensation structures could be realized with periodic array by graphene material.The propagation model of period folds excited SPPs and the full compensation were analyzed theoretically.The results of theoretically analysis show that the period fold structure can not only excite SPPs,but also control device parameters using SPPs wave relations.In addition,periodic array compensation can significantly increase the propagation distance of SPPs.Further simulation results show that the proposed structure has the advantage of strong localized and subwavelength waveguide size;periodic array compensation can significantly improve the electric field strength of nanocavity;structure of graphene waveguide expresses high levels of population inversion and low spontaneous emission noise disturbance.The proposed graphene waveguide devices can be provided for the micro-nano optics, photonic sensing and measurement.
