According to the requirements of the increasing development for optical transmission systems, a novel construction method of quasi-cyclic low-density parity-check (QC-LDPC) codes based on the subgroup of the finite field multiplicative group is proposed.

本文提出了一种新的实现双频双模He-Ne激光器稳频稳幅的干涉方法.
Quantitative knowledge of the film thickness and mass fraction of the urea–water solution is very crucial in many practical applications. Film thickness or mass fraction can only be determined individually by conventional measurement techniques. We develo
Stimulated Raman scattering (SRS) excited by incoherent light is studied via particle-in-cell simulations. It is shown that a large bandwidth of incoherent light can reduce the growth of SRS and electron heating considerably in the linear stage. However,
从贝尔实验室的阿瑟士(A. Arthnz)首次演示激光悬浮以来的十年间,涉及这一课题的只有少量零星的实验报告。最近几篇文章是法国的奥赛光学研究所的罗森(G. Roosen)发表的,他继续研究并改进了用辐射压力使微粒稳定悬浮的技术。他正在从事光悬浮的一些应用研究,其中包括激光核聚变实验靶的无接触悬浮。现在纽约工学院和芒特西奈(Mount Siuai)医学院的研究者们,用辐射力悬浮微粒,观察到另一种不同的类似现象。这一技术将为应用广开门路。

We demonstrate a fiber refractive index (RI) sensor based on an excessively tilted fiber grating (ExTFG) immobilized by large-size plasmonic gold nanoshells (GNSs). The GNSs are covalently linked on ExTFG surface. Experimental results demonstrate that bot
采用达布变换法得到了标准非线性薛定谔方程的一阶呼吸子解及其怪波极限,研究了一阶呼吸子解的动力学特性。借助达布变换的递推关系得到了非线性薛定谔方程的高阶呼吸子解,并分别研究了碰撞叠加、分离、简并和并行传输模式。当各呼吸子的频率趋于零时,得到非线性薛定谔方程怪波极限。研究结果表明,怪波幅值、凸起数以及怪波分裂后中心波峰的阶数和周围的波峰个数均与怪波阶数有关。
