Silicon has been the material of choice of the photonics industry over the last decade due to its easy integration with silicon electronics, high index contrast, small footprint, and low cost, as well as its optical transparency in the near-infrared and p

We investigate the linear momentum density of light, which can be decomposed into spin and orbital parts, in the complex three-dimensional field distributions of tightly focused vortex segmented beams. The chosen angular spectrum exhibits two spatially se
We discuss a merit function F as judgment of photo-thermal conversion efficiency instead of two independent parameters: solar absorptance \alpha and thermal emittance \varepsilon. The merit function F is developed using Essential Macleod software to op
马耳文（Malvern)英国皇家雷达研究中心在研究一种产生高能短激光脉冲的方法。短于产生激射作用所需的临界长度的两根晶体棒分别受到“泵浦”，然后按光学方法耦合在一起. 能量在一个长时间内泵入两根短棒，当两棒耦合时，在一个很短的时间内释放出来。

In order to obtain good optical characteristics in the GaN-based vertical-cavity surface-emitting laser (VCSEL), different kinds of AlGaN electron blocking layers (EBL) were introduced. These were inserted coherently near the active region to limit electr

本文延伸通常的固体电子结构计算,根据通常计算所得到的微观物理量以计算固体光学常数等宏观物理量.并以金属Gd为例,给出了简化模型下计算出的理论吸收谱.
Attribution of Fano resonant features to plasmonic particle size, lattice constant, and dielectric w
Fano resonances between plasmons and diffracted light offer tunable energies and locales, but attribution of Fano resonance features to geometry and physicochemistry of metal nanostructures and adjacent dielectrics has been confounded by complexity and co
