Optical Phased Arrays on Photonic Integrated Circuit Platforms: Challenges, Opportunities, and Future Applications

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Integrated optical phased arrays are emerging as scalable engines for solid‐state beam steering and programmable wavefront control. This Review maps the field from beam‐steering principles and core building blocks to material platforms, system‐level bottlenecks, and application frontiers, highlighting how heterogeneous integration, aperiodic ...

Space‐Time‐Coding Metasurfaces Enabling Programmable Range‐Angle‐Dependent Energy Auto‐Scanning

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
This paper presents a novel energy auto‐scanning system based on a space‐time‐coding metasurface. By applying progressive time‐delayed, time‐varying phase modulation, the system generates non‐uniform, temporally evolving electromagnetic field distributions across both angle and range.

Fully Polarimetric Radar Cross‐Section and High‐Resolution Range Profile Co‐Modulation via Diversely Time‐Modulated Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...

Sub‐Ensemble Isolation in SERF Magnetometry Enabled by Micrometer‐Scale Polarization Control

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Inter‐channel crosstalk caused by atomic diffusion fundamentally limits the spatial resolution of single‐cell multi‐channel SERF magnetometers. In this work, a spatial‐variant polarization metasurface is employed to achieve effective sub‐ensemble isolation within a single SERF atomic ensemble, which enables the suppression of inter‐channel crosstalk ...

Three‐Dimensional Array Multicasting of Cylindrical Vector Beams Using Spin‐Multiplexed Dammann Vortex Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
This study demonstrates, for the first time, a 3D volumetric cylindrical vector beam (CVB) multicasting architecture that employs multichannel array modes with an operational dimension of 3 × 3 × 5 as information carriers. This approach offers substantial potential for high‐capacity information dissemination in mode‐multiplexed communication networks ...
