【摘要】

：

提出了在单模光纤联接的望远镜干涉阵中通过拉伸红外单模光纤实现光程调制的方法.简要分析了该方法的机理及存在的问题，如偏振效应、色散等.用少模光纤和单模光纤分别代替马赫-陈德尔(Mach-Zehnder)干涉仪的两个臂，并且其中一臂的光纤缠在直径为6 cm的PZT圆柱上.给PZT圆柱施加三角波电压后，首次得到干涉条纹，并证明了方法的可行性.

Absorption saturation measurement using the tapered optical nanofiber in a hot cesium vapor

We report the observation of ultralow-power absorption saturation in a tapered optical fiber (TOF) mounted in a hot cesium (Cs) vapor in a vacuum chamber. The small optical mode area of TOF produces a great influence on optical properties, allowing optica

求解Helmholtz方程的新型稀疏近似逆预条件算法

提出了一种新型预条件算法, 用于对有限元法离散Helmholtz方程所产生的大型稀疏复对称且高度不定的线性系统进行高效迭代求解。该新型预条件子是在复拉普拉斯偏移算子的基础上结合改进的稀疏近似逆算法来得到。通过改善矢量有限元线性系统自身的谱特性, 该预条件算法既可避免迭代中的不稳定情况, 同时也能较大提高迭代求解效率。数值结果表明, 与若干常用预条件算法相比, 所提出的预条件算法更加有效。

Enhanced NIR emission in Ce3 /Er3 -doped YAG induced by Bi3 doping

Ce3 /Er3 /Bi3 triply-doped yttrium aluminum garnet (YAG) is synthesized using co-precipitation method. The Bi3 concentration-dependent near-infrared (NIR) emission behavior is systemically investigated. The NIR emission of Er3 ions at 1531 nm is enhanc

All-dielectric three-element transmissive Huygens’ metasurface performing anomalous refraction

Metasurfaces have pioneered a new avenue for advanced wave-front engineering. Among the various types of metasurfaces, Huygens’ metasurfaces are thought to be a novel paradigm for flat optical devices. Enabled by spectrally overlapped electric resonance a

Quantum nonreciprocality in quadratic optomechanics

We propose to achieve nonreciprocal quantum control of photons in a quadratic optomechanical (QOM) system based on directional nonlinear interactions. We show that by optically pumping the QOM system in one side, the effective QOM coupling can be enhanced
