Nanosecond, Nanometer Movies of MEMS/NEMS Dynamics in a Standard SEM Using Time‐Tagged Secondary Electrons

open access: yesSmall Methods, EarlyView.
For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

Dynamic Control of Phase Matching in Nonlinear Metasurfaces Using Pancharatnam–Berry Phase

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
Can mechanical rotation of a metasurface control the phase of a nonlinear optical signal? In a dual‐metasurface multipass cell, a circularly polarized pump interacts repeatedly with two plasmonic metasurfaces between two mirrors. By exploiting the geometric phase, rotating one metasurface shifts the phase‐matching condition of the second‐harmonic ...

Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
A silicon photonic beam steerer based on a metalens focal plane array (FPA) monolithically integrates the collimation lens on‐chip while enabling blind‐spot‐free continuous beam steering. Thermo‐optic prisms provide continuous fine‐tuning and more than double the number of resolvable points.
