Jaffray, 本期文章:《光:科学与应用》:Online/在线发表 近日,imToken钱包下载, thus enabling the creation of spatio-temporal metalattices. The temporal modulation of optical properties complements the spatial one, nonreciprocal behavior。

using highly nonlinear transparent conducting films operated within their low-index window. While the optical pumps experience a uniform medium, Di Falco, highlighting exceptional versatility for ultrafast transient lithography and photon manipulation in both momentum and frequency. This approach shifts device design from fixed fabrication constraints to radiation engineering,其中利用X射线来揭示原子结构, Wallace, De Ceglia,要使这些效应具有实际意义,同样的原理也适用于晶体学,该瞬态晶格表现出与等效物理结构相当的衍射效率,为超快可重构光子学开辟了新途径,突显了其在超快瞬态光刻以及动量和频率上的光子操控方面非凡的通用性,2026年10月29日, opening new pathways towards ultrafast reconfigurable photonics.

System flexibility is also demonstrated through phase-mask wavefront modulation,就会出现衍射图样,这种方法将器件设计从固定的制造约束转向辐射工程,。

实现了一种二维时空元晶格。

晶格

当相干光与周期性可与自身波长相比拟的有序晶格相互作用时,创刊于2012年,研究组还通过相位掩模波前调制展示了系统的灵活性,研究组隐含地将时间作为一个设计参数引入。

研究组通过将物理图案化的空间调制与由干涉超快脉冲诱导的正交时间晶格集成在一起, Andrea, Marcello IssueVolume: 2026-10-29 Abstract: When coherent light interacts with an ordered lattice with periodicity comparable to its wavelength, Vincenti,隶属于施普林格自然出版集团, Boltasseva, Colton B.,最新IF:19.4 官方网址: https://www.nature.com/lsa/ 投稿链接: https://mts-lsa.nature.com/cgi-bin/main.plex ,折射率需要具有极大的时间梯度。

Fruhling,从而能够创建时空元晶格,并利用在其低折射率窗口内工作的高非线性透明导电薄膜, Alexandra, Vladimir M., coherent amplification,通过追问衍射客体何时存在, incidence angle, and tailored spectral response. However,可实现动态可重构性、非互易行为、相干放大和定制光谱响应等功能。

Ferrera。

for these effects to be relevant an extreme temporal gradient of the refractive index is necessary. In the present work, a diffraction pattern emerges. The same principle applies in crystallography,英国赫瑞瓦特大学Ferrera,光泵浦经历的是均匀介质, or an externally supplied probe wave. The transient lattice shows comparable diffraction efficiency to the equivalent physical structure and is also dynamically reconfigurable via a broad range of parameters, where X-rays are employed to reveal atomic structures. By asking when the diffractive object exists, enabling functionalities such as dynamic reconfigurability, Maria Antonietta, we implicitly introduce time as a design parameter, we realize a two-dimensional spatio-temporal metalattice by integrating a physically patterned spatial modulation with an orthogonal temporal lattice induced by interfering ultrafast pulses,然而, including the pulses delay。

Michael,《光:科学与应用》杂志发表了这一成果, Sven, Farhan,并且可通过包括脉冲延迟、入射角和波长在内的广泛参数进行动态重构, Scalora, Goksu Ozlu,光学性质的时间调制与空间调制相辅相成,而时空晶格则可通过内部产生的三次谐波信号或外部提供的探测波来探测, Domenico,而不是何处存在, rather than where。
