High‐Endurance and Energy‐Efficient All‐Optical Programming of Scalable Silicon Waveguides with Integrated Phase‐Change Material Patches

Advanced Optical Materials, EarlyView.
Phase change materials are integrated into silicon photonic circuits via 200 mm industrial wafer processes. Interferometric optical characterization reveals switching thresholds, transmission modulation, phase shifts, and record endurance (>108 cycles).

Thermal‐Energy‐Boosted Luminescence for Precise Optical Thermometry in Eu/Tb‐Doped ScNbO4

Advanced Optical Materials, EarlyView.
This paper presents a novel phosphor for high‐performance optical thermometry utilizing thermal‐energy‐assisted luminescence boosting. The samples are prepared by incorporating Eu‐doped ScNbO4 and Tb‐doped ScNbO4 powders into a PDMS matrix. Under blue light excitation, the sample exhibits a stunning emission color change from green to red as the ...

Enhanced THz Emission From Ultrathin Ta/Fe/Pt Spintronic Trilayers

Advanced Optical Materials, EarlyView.
Ultrathin Ta/Fe/Pt spintronic trilayers on MgO(100) substrates generate intense terahertz (THz) emission under femtosecond laser pulse excitation. Constructive interference of the emitted THz waves from Ta and Pt layers is maximized through crystallographic engineering of the Ta layer into a high‐resistivity fcc phase and optimization of the trilayer ...

Broadband Measurement and Tuning of the Volatile Thermo‐Optic Properties in Chalcogenide Phase Change Materials

Advanced Optical Materials, EarlyView.
Chalcogenide phase change materials (PCMs) demonstrate a significant switchable volatile thermo‐optic response across visible and telecommunication bands. A broadband measurement is presented showing that some alloys exceed traditional reconfigurable materials in photonic integrated circuit (PIC) applications.

Molybdenum‐Doped Nickel Oxide as an Advanced Ion Storage Layer for Highly Stable and Durable Flexible Electrochromic Devices

Advanced Optical Materials, EarlyView.
An optimized Mo‐doped NiO (MNO) film is developed using a magnetron sputtering process to overcome the limitations of pristine NiO in electrochromic (EC) applications. The MNO film exhibits improved optical modulation, faster response time, and enhanced cycling stability compared to pristine NiO.
