基于石墨烯的空分复用光孤子
Graphene-based Solitons for Spatial Division Multiplexed Switching
摘要：
空分复用利用光传播k矢量的方向性将其分离成不同的空间方向。在这里，我们表明，在一个单一的石墨烯单层的正交空间孤子传播的各向异性的相位为基础的复用结果。我们利用空间孤子的自限制特性来增加这种开关系统的可用态密度。此外，我们表明，交叉两个正交孤子表现出低（0.035 dB）的相互干扰，从另一个独立的k矢量开关。DOS的有效利用和实空间中的多路复用使数据处理与光网络和计算中的应用并行。
英文摘要：
Spatial division multiplexing utilizes the directionality of lights propagating k-vector to separate it into distinct spatial directions. Here we show that the anisotropy of orthogonal spatial Solitons propagating in a single Graphene monolayer results in phase-based multiplexing. We use the self- confinement properties of spatial Solitons to increase the usable density of states (DOS) of this switching-system. Furthermore, we show that crossing two orthogonal Solitons exhibit a low (0.035 dB) mutual disturbance from another enabling independent k-vector switching. The efficient utilization of the DOS and multiplexing in real-space enables data processing parallelism with applications in optical networking and computing.
