近日,美国CFD计算流体力学研究公司Arturo Martin Jimenez,Zachary J. Coppens团队在Nature Photonics上发文,利用纳米结构双折射超表面光学元件,实现了低延迟、紧凑形式的相位多样性波前传感。
Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, ...
MBI团队提出了创新性解决方案:在脉冲产生方面,采用“孤子自压缩”技术。简单来说,当激光脉冲在充气的空心光纤中传播时,气体的光学克尔效应与反常色散相互平衡,形成“光孤子”——能够在传播中保持形状的特殊波包。巧妙的是,当孤子的频谱展宽到特定波长时,会发 ...
Instead of relying on switches or digital control, the light finds its own path through the system. This approach could transform data transmission, computing, and communications by making optical ...
Researchers at University of Tsukuba have successfully measured electric fields near the surfaces of two-dimensional layered ...
这项研究开发的设备是一种小型硅芯片,可用作智能收发器:它们成对工作,能够自动、独立地 "计算 "光束的形状,以便以最高效率穿过一般环境。这还不是全部:它们还能产生多束重叠的光束,每束光束都有自己的形状,并在不相互干扰的情况下引导它们,通过这种方式,传输能力大大提高,这正是下一代无线系统所需要的。

Researchers from NTNU and EPFL have unveiled a compact, low-cost laser that outperforms current models in speed, control, and ...
深夜,复旦大学化学楼实验室,博士生张璐正在对斑马鱼进行显微注射操作。一个手滑,斑马鱼的眼睛“蹦”了出来。瞬间的惊悚和长期积压的疲惫交织,让张璐的情绪骤然失控,又哭又笑,吓坏了一旁的师兄。
A new photonics chip that generates multicolored laser beams could supercharge data center technology and ease the strain of ...
The first Dutch national eDNA workshop marked a turning point in how the Netherlands approaches biodiversity monitoring.
北京时间10月15日晚,在最新一期的顶刊Nature上,清华大学的方璐带领团队发表了最新研究成果。该研究报道了用于亚埃级快照光谱学的集成铌酸锂光子学。传统光谱技术依赖窄缝或光栅,在光谱分辨率与光通量之间必须做出权衡,难以同时实现高灵敏度与高效率。该研 ...
