Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array
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.

This work constructs a radio‐frequency front‐end‐free hybrid code‐division and space‐division‐multiplexing wireless communication system built on programmable space‐time‐coding metasurfaces. Orthogonal pseudo‐random codes reliably separate overlapped multistream signals that share identical frequency, time, and spatial resources.

A unified fiber‐wireless integrated sensing and communication system is enabled by a single microwave photonic platform with a time‐phase synthesis dimension waveform. This architecture simultaneously delivers high‐speed data transmission, high‐precision wireless ranging, and accurate fiber diagnostics over a high‐power analog radio‐over‐fiber link ...

We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.

During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.
