Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex generators. However, it is often required to segment or interleave independent sub-array metasurfaces to multiplex optical vortices in a single nano-device, which in turn affects the device’s compactness and channel capacity. Here, inspired by phyllotaxis patterns in pine cones and sunflowers, we theoretically prove and experimentally report that multiple optical vortices can be produced in a single compact phyllotaxis nanosieve, both in free space and on a chip, where one meta-atom may contribute to many vortices simultaneously. The time-resolved dynamics of on-chip interference wavefronts between multiple plasmonic vortices was revealed by ultrafast time-resolved photoemission electron microscopy. Our nature-inspired optical vortex generator would facilitate various vortex-related optical applications, including structured wavefront shaping, free-space and plasmonic vortices, and high-capacity information metaphotonics.
High-throughput computational imaging requires efficient processing algorithms to retrieve multi-dimensional and multi-scale information. In computational phase imaging, phase retrieval (PR) is required to reconstruct both amplitude and phase in complex space from intensity-only measurements. The existing PR algorithms suffer from the tradeoff among low computational complexity, robustness to measurement noise and strong generalization on different modalities. In this work, we report an efficient large-scale phase retrieval technique termed as LPR. It extends the plug-and-play generalized-alternating-projection framework from real space to nonlinear complex space. The alternating projection solver and enhancing neural network are respectively derived to tackle the measurement formation and statistical prior regularization...
Call for papers
The Editors-in-Chief invite authors to submit manuscripts for consideration in this journal.
As a highly selective publication forum, every year eLight will only publish 52 original research articles and review articles in total. Every published work is anticipated to fundamentally push the frontiers of the respective research field.
EiCs, Editorial Board Members and professional team will ensure fast, rigorous and fair peer review, with an estimated turnaround time of 30 days. Each paper will be accompanied with an invited Commentary, e-cover and public communication through various press release channels and the social media. The whole eLight team, co-managed by CIOMP and Light: Science & Applications, would provide prompt publication, multi-channel outreach, an option to transparent peer review, and free-of-charge open access (till the end of 2022). We will also hold an annual event for Best Paper Award, in conjunction with an international eLight Conference.
Both review and original research papers are welcome. Look forward to your contributions! Please do not hesitate to contact us if you have any questions and/or suggestions.
