We present a low cost radio-frequency (RF) generator suitable for experiments with cold atoms. The RF source achieves a sub-hertz frequency with tunable resolution from 0 MHz to 400 MHz and a maximum output power of 33 dBm. Based on a direct digital synth
The Bell-nonlocality of two initially entangled macroscopic fields in the double Jaynes-Cummings model is investigated. Moreover, the process by which detuning between the atomic transition frequency and the field frequency affects the evolution of the Be
针对菱形晶格多孔光纤，应用全矢量有限差分光束传播法分析了纤芯附近一对特殊气孔、本底气孔以及对角线上的气孔间距对偏振拍长波长敏感性的影响，初步得出包层结构的优化参数，再通过横向伸缩形变引入两种新的非对称结构，进一步抑制多孔光纤原有双折射随波长的非线性变化，在降低偏振拍长波长敏感性的同时包层结构的几何参数也获得了较大的误差容限，结果表明，偏振拍长的中值为132.5 mm，在波长1.2～1.7 μm范围内，相对变化率小于±4%，同时优化后包层结构的几何参数误差容限大于0.1 μm，为制作多孔光纤宽带消色差波片提

Total loss test of the high-reflective (HR) film coated on super-smooth silica substrate by dual ion beam sputtering (DIBS) is based on the well-established cavity ring-down technique. Scattering and transmittance are tested by integral scattering and tra
Hybrid perovskite materials are widely researched due to their high absorptivity, inexpensive synthesis, and promise in photovoltaic devices. These materials are also of interest as highly sensitive photodetectors. In this study, their potential for use i
We investigate the diffraction of the guided modes of a dielectric slab waveguide on a simple integrated structure consisting of a single dielectric ridge on the surface of the waveguide. Numerical simulations based on aperiodic rigorous coupled-wave anal
Aerogel materials manufactured from metal oxides have been used as components in numerous high-energy density physics targets. These aerogels have been identified to be used as a future target material in the AWE fielded campaigns at the US National Ignit
A new method is proposed for the object surveillance system based on the enhanced fish-eye lens and the high speed digital signal processor (DSP). The improved fish-eye lens images an ellipse picture on the charge-coupled device (CCD) surface, which incre
We present an experimental demonstration of notch filters with arbitrary center wavelengths capable of tunable analog output power values varying between full extinction of 15 and 0 dB. Each filter is composed of highly modular apodized four-port Bragg ad
