[其它] Soliton mode-locked fiber laser based on topological insulator Bi

说明：We reported diverse soliton operations in a thulium/holmium-doped fiber laser by taking advantage of a tapered fiber-based topological insulator (TI) Bi2Te3 saturable absorber (SA). The SA had a nonsaturable loss of ～53.5% and a modulation depth of 9

[其它] 基于网络编码的无线传感器网络生存时间最大化

说明：结合网络编码理论,研究了无线传感器网络生存时间的最大化问题。首先,基于物理层广播特性提出了一种新的超图模型,用以描述无线传感器网络中基于网络编码的信息传输;并在此模型基础上,提出了一种基于超弧的网络能耗线性测量模型,将无线传感器网络生存时间的最大化问题描述成为多约束条件下的网络流量优化分配问题。实验结果表明:本文提出的优化问题更符合无线传感器网络中信息传输的本质特征,能够为基于无线广播的网络编码实现合理的资源分配。此外,在无线传感器网络中应用网络编码确实可以提高整个网络的生存时间。

[其它] Sign of differential reflection and transmission in pump-probe spectroscopy of graphene on dielectric substrate

说明：Pump-probe differential reflection and transmission spectroscopy is a very effective tool to study the nonequili-brium carrier dynamics of graphene. The reported sign of differential reflection from graphene is not explicitly explained and not consis

[其它] Graphene surface plasmon polaritons transport on curved substrates

说明：We theoretically investigate the transport property of graphene surface plasmon polaritons (GSPPs) on curved graphene substrates. The dispersion relationship, propagation length, and field confinement are calculated by an analytical method and compar

[其它] Experimental far-field imaging properties of high refractive index microsphere lens

说明：The far-field imaging properties of a high index microsphere lens spatially separated from the object are experimentally studied. Our experimental results show that, for a Blu-ray disk whose spacing is 300 nm, the high index microsphere lens also can

[其它] Introduction to the Photonics Based on Two-dimensional Materials feature issue

说明：We propose and demonstrate a dual-wavelength single-longitudinal-mode (SLM) fiber laser with switchable wavelength spacing based on a graphene saturable absorber (GSA) and a WaveShaper. By virtue of the excellent saturable absorption ability of graph
