Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Advanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Rapid Electro‐Thermal Micro‐Actuation of Flat Optics Enabled by Laser‐Induced Graphene on Colorless Polyimide Substrates

Advanced Optical Materials, EarlyView.
Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...

Extreme Terahertz Nonlinearity of AlGaN/GaN‐Based Grating‐Gate Plasmonic Crystals

Advanced Optical Materials, EarlyView.
Plasmonic crystals based on grating‐gated 2D electron gas in AlGaN/GaN heterostructures provide a platform for strong light‐matter interaction. Pump‐probe experiments revealed strong terahertz nonlinearity leading to 45% increase in transmission at a fluence below 350 nJ cm−2.

Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles

Advanced Optical Materials, EarlyView.
Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.
