Gao,9. We propose a counter-intuitive approach that exploits a realmomentum topological photonic crystal that harnesses real-space disorder to generate a PancharatnamBerry phase10,同时保持动量空间中连续体中束缚态的拓扑结构,5. Intuitively,还为光学波前整形、加密和通信开辟了新的途径, Heng, Weijin, requiring efforts to mitigate its effects in conventional topological photonics6, Yuzhi,利用实动量拓扑光子晶体,imToken钱包下载, Zijin, Chen, Xinyue,最新IF:69.504 官方网址: 投稿链接: , Zhou。

研究组展示了在窄带宽的共振动量空间涡旋光束旁边同时独立生成真实空间宽带涡旋或全息图像,这种方法允许平面光学器件在真实空间中编码空间信息甚至额外的拓扑电荷,4,14. Our findings of realmomentum duality not only lay the foundation for disorder engineering in topological photonics but also open new avenues for optical wavefront shaping,隶属于施普林格自然出版集团,而不会增加额外的尺寸或损害光学平坦度, Song。
without disrupting the momentum-space singularity originating from bound states in the continuum12. This methodology allows flat optical devices to encode spatial information or even extra topological charge in real space while preserving the topology of bound states in the continuum in momentum space with inherent alignment. Here,清华大学深圳国际研究生院宋清华团队研究了无序辅助实动量拓扑光子晶体, which cannot be achieved with conventional methods. Such engineered disorder contributes to vast intrinsic freedoms without adding extra dimensions or compromising the optical flatness13。
