提出了一种纳米结构硫族化物-金属光纤。这种混合纳米纤维嵌入了以领结结构设置的三角形深亚波长金属（或半导体）纳米线的周期性阵列。计算表明，所提出的纳米结构光纤支持引导集体等离子体模式，从而实现亚波长场限制和极端非线性光与物质相互作用。还提出了一种方案，当使用半导体单壁碳纳米管代替金属时，通过非线性光学增益补偿大的线性吸收损失。
A nanostructured chalcogenide-metal optical fiber is proposed. This hybrid nanofiber is embedded with a periodic array of triangular-shaped deep-subwavelength metallic (or semiconductor) nanowires set up in a bowtie configuration. Calculations show that the proposed nanostructured fiber supports a guided collective plasmonic mode enabling both subwavelength field confinement and extreme nonlinear light-matter interactions. A scheme is also proposed whereby the large linear absorption losses are compensated via nonlinear optical gain when semiconducting single-wall carbon nanotubes are used in place of metal.
