The release of the Orion prototype and the momentum it has brought have enlivened the SiC supply chain, prompting it to focus on developing and expanding optical grade SiC. 这一转变的时机可能表明,目前存在理想的条件,可以从200毫米基础设施开始,迅速向300毫米发展,以增加产量并进一步降低成本,从而为首次...
However, for forward designed meta-optics an optical designer has to strongly rely on experience and intuition about the functionality of the meta-optics. As such, this method does not provide a clear path to further improve the imaging quality. Unlike forward design, inverse design approaches def...
超透镜又薄又平,可以取代厚重的曲面透镜,有望彻底改变光学产品。超透镜是下一代紧凑型成像、传感和显示应用的关键技术[1]。为了助力这个全新创新领域的发展,新思科技推出了 MetaOptic Designer。这是一款强大的逆向设计工具,让用户可以根据自己指定的标准来生成超透镜/超表面,从而实现出色的系统性能。
Second, we discuss the application of these ideas to the physics of optical metasurfaces with broken-symmetry meta-atoms when tuning to the BIC conditions allows to enhance substantially the Q factor of the structure. In this section, we also present the original results about nonlinear high-Q ...
The metaverse has captured significant attention as it provides a virtual realm that cannot be experienced in the physical world. Programmable optical holograms, integral components of the metaverse, allow users to access diverse information without need
日前,美国专利商标局公布了一份来自Facebook的专利申请,其主要描述了一种减少彩虹伪影的光学系统。具体来说,名为“Optical device having reduced diffraction artifacts for eye-tracking”主要介绍一种能够抑制彩虹伪影的光栅构造。 在一个实施例中,光学装置可以包括光栅。光栅可以包括至少一个基板和耦合到至少一个基板的...
我们提出了用于深度神经网络(DNN)训练的新型直连交换结构 TOPOOPT。它结合计算、通信和网络拓扑三个维度共同优化分布式训练过程。我们演示了 AllReduce 流量的可变性,并利用此属性为 DNN 训练作业构建高效的网络拓扑。然后,TOPOOPT 使用交替优化技术和名为 TotientPerms 的群论启发算法,结合并行化策略,找到最佳网络拓扑和...
The meta-optical elements were constructed using high-index chalcogenide films deposited on fluoride substrates: the choices of wide-band transparent materials allow the design to be scaled across a broad infrared spectrum. Capitalizing on a two-component Huygens’ meta-atom design, the meta-optical ...
