Bandgap Tuning of β‐(AlxGa1‐x)2O3 Nanosheets via Liquid Metal Interface Engineering

Advanced Optical Materials, EarlyView.
Ultrathin β‐(AlxGa1‐x)2O3 nanosheets with controlled composition are synthesized via low‐temperature squeeze‐printing of Al─Ga liquid alloys. Aluminium preferentially migrates to the surface of the liquid alloy, forming Al‐rich oxide layers with tunable bandgaps up to 6.4 eV. This compositionally precise approach enables the fabrication of 2D ultrawide‐

Nanoimprinting of Mesoporous Titania: Direct Patterning and Refractive Index Control in the Visible

Advanced Optical Materials, EarlyView.
Nanoimprinted mesoporous TiO₂ (pTiO₂) films are demonstrated as high‐resolution optical materials with tunable porosity, refractive index, and mechanical response. Sub‐micron patterning of planar optics is shown alongside a refractive index contrast Δn ≈0.7.

Optical Chaos Generation and Applications

Advanced Photonics Research, EarlyView.
This review comprehensively examines optical chaos generation via feedback, injection, and optoelectronic methods, emphasizing bandwidth enhancement and time‐delay suppression. Applications include chaos‐synchronized secure communication, physical random number generation, chaotic lidar for cm‐level detection, distributed fiber sensing, and terahertz ...

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.

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.
