Scale‐Invariant Waveguiding in Flatland

open access: yesExploration, EarlyView.
The study introduces scale‐invariant metasurface waveguides with uniform modal field distribution and an effective index independent of the core width. By leveraging spatial symmetry and fine‐tuning mode profiles, the design is validated through near‐field measurements in the C band, offering potential applications in flat optics, sensing, and ...

Multi‐dimensional, multi‐interfacial, and multi‐path synergy enables broadband absorption, corrosion resistance, Joule heating, and thermal performances in hierarchical carbon/Ni nanoparticles‐carbon nanocoils foams

open access: yesInfoMat, EarlyView.
Owing to the severe electromagnetic wave (EMW) pollution and the increasingly intricate operating environments, an excellent EMW absorber with multiple functions has become imperative. Herein, 3D/0D‐1D hierarchical carbon/Ni nanoparticles‐carbon noncoils (CNCs) composite foams with multi‐dimensional, multi‐interfacial and multi‐path structures can be ...

Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

open access: yesInfoMat, EarlyView.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...

Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

open access: yesLaser &Photonics Reviews, EarlyView.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...
