Breaking the Bottleneck in Limit of Detection of Surface Refractive Index Sensing by Harnessing Meta‐Waveguide Microring Resonators

open access: yesAdvanced Science, EarlyView.
Mode splitting in meta‐waveguide microring resonators (MWMRs) effectively suppresses baseline drift and measurement noise while maintaining high refractive‐index sensitivity. This reflection‐induced mode splitting strategy enables quantitative detection of ultra‐weak surface perturbations and establishes MWMRs as a robust, drift‐immune platform for ...

Helical Electron Beam Micro‐Bunching by High‐Order Modes in a Micro‐Plasma Waveguide

open access: yesAdvanced Science, EarlyView.
ABSTRACT Electron acceleration by a high‐power Laguerre‐Gaussian pulse in a micro‐plasma waveguide is investigated. When the incident laser travels in the waveguide, electrons on the wall are extracted into the vacuum core and accelerated by the longitudinal field of the waveguide mode.
