Switchable Terahertz Beam Steering with Near‐Perfect Ordinary Transmission

Advanced Photonics Research, EarlyView.
This study introduces a reconfigurable metasurface that enables switchable terahertz beam steering upon actuation by a global temperature change. At room temperature, it achieves a true “OFF” state with nearly 100% transmission, behaving as if the metasurface is not present, thereby not distorting incoming light.

Thermal Shrinkage‐Induced Modifications in Photonic Bandgaps of Two‐Photon Polymerized Bragg Reflectors

Advanced Photonics Research, EarlyView.
Scanning electron microscopy and white‐light reflectance images of the pillar‐supported distributed Bragg reflector (DBR) are presented before and after thermal shrinkage. The DBR, fabricated via two‐photon polymerization, consists of alternating high‐ and low‐index layers supported by vertical pillars.

Floquet‐Engineered Noise‐Resilient Terahertz Receiver with Modular Phased Array Architecture for Scalable Chip‐Scale Communication

Advanced Photonics Research, EarlyView.
Overcoming the bandwidth, latency, and power constraints of wired interconnects in multicore processing units, this work introduces a terahertz wireless solution featuring a dual‐carrier modular phased‐array transmitter and a novel 2D semiconductor quantum‐well nanoreceiver.

Ultralow Loss Coupling Tuning of Photonic Accelerators

Advanced Photonics Research, EarlyView.
A polymer material cured by electron beam is used to perform precise and ultralow loss tuning on photonic accelerators made for highly efficient computation. The versatility of the technique is demonstrated on a large number of directional coupler devices with varying initial coupling ratios and application on a crossbar array for matrix multiplication

Effect of Atomic Charges on C2H2/CO2/CH4 Separation Performances of Covalent‐Organic Framework Adsorbents

Advanced Theory and Simulations, EarlyView.
Three charge assignment approaches (one quantum chemistry method‐based, the other two machine‐learning (ML) model‐based) are employed to investigate acetylene separation performances of experimental covalent‐organic frameworks. Partial Atomic Charge Predicter for Porous Materials based on Graph Convolutional Neural Network (PACMAN) ML model‐based ...
