This paper describes a new multi-layer complex liquid-cooled Si mirror with 3 cooling ducts in Archimedes spirals. Utilizing the ANSYS program, the structure of the mirror is optimized and the thermal deformation model of the mirror is simulated. The simulation results show that the mirror has the following advantages: very small amount of surface deformation, uniform distribution of temperature and surface deformation, and fast surface shape restoration. The results of the experiments of thermal deformation and the surface restoration are accurately mapped to the simulation results.

We describe a polarization rotator based on a parallel-core structure consisting of a silicon nanowire waveguide and a silicon-nitride waveguide. The 60-μm-long rotator provides a polarization extinction ratio of more than 10 dB with excess loss of less t
星载气辉成像干涉仪采用临边观测模式, 可以获取全球范围内大气风场的空间分布信息及时间演化信息, 是国际卫星遥感领域的研究热点。基于O3辐射源的Michelson星载成像干涉仪在红外波段工作, 能够全天时探测平流层区域的大气风场, 却存在更为复杂的测风不确定度。鉴于此, 在临边观测正演仿真的基础上, 开展了仪器热背景辐射研究及测量噪声分析, 给出了大气信号测量噪声及仪器热背景噪声引起的大气风场速度误差数值, 并通过表观量仿真及信噪比分析, 得到了视向风的误差廓线。不确定度分析表明, 基于O3辐射源的Mich
Optical links are moving to higher and higher transmission speeds while shrinking to shorter and shorter ranges where optical links are envisaged even at the chip scale. The scaling in data speed and span of the optical links demands modulators to be conc
We investigate the superposition properties of the dipole and quadrupole plasmon modes in the near field both experimentally, by using photoemission electron microscopy (PEEM), and theoretically. In particular, the asymmetric near-field distributions on g
在87Rb冷原子系综中,利用自发Raman散射过程实现了光与原子纠缠。通过选择两个不同的跃迁频率的读光对存储的自旋波进行读出,在两种不同读光频率下测量了读出效率以及Bell参数S值。结果发现在读光功率相同的条件下其中一种读光频率的读出效率为18％,Bell参量S值为2.68。另一种读光频率的读出效率达到38％,Bell参量S值为2.5。本文的研究成果为产生高质量的光与原子纠缠源提供了实验基础。

洛斯·阿拉莫斯国家实验室的普里德霍斯基(W. Priedhorsky)和他的同事们说，他们用CO2激光脉冲辐照了高原子序数聚变靶。对于靶发出的硬X射线所作的首次测量表明，吸收的激光能量大部分被转化成高能电子。这对于用CO2激光器作为聚变驱动器的拥护者们是个坏消息，因为那些“热”电子会把它们的能量沉积到燃料中，从而妨碍点燃热核燃烧所需的靶压缩。普里德霍斯基告诉记者，“关于热电子是CO2激光聚变的最大问题,我们早就知道，但是,这些实验告诉我们，这个问题比我们想象的还要糟。”
