Confinement‐Induced Nonlocality and Optical Nonlinearity of Transdimensional Titanium Nitride Films in the Epsilon‐Near‐Zero Region

Advanced Optical Materials, EarlyView.
The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

Nanopatterned Dual‐Carbon‐Dot Photonic Films With Enhanced Light Outcoupling

Advanced Optical Materials, EarlyView.
Nanoimprinted dual‐carbon‐dot/PVA films combine composition‐tunable blue–green emission with grating‐mediated directional light outcoupling. Water‐processable B‐CD and G‐CD composites are patterned by drying‐assisted nanoimprinting, producing angle‐selective emission peaks that follow the first‐order diffraction condition and exhibit reference ...

1.5 µm Emission Properties of Erbium‐Implanted Thin‐Film Lithium Niobate

Advanced Optical Materials, EarlyView.
Optically active Er3+ ions are incorporated into x‐cut lithium niobate on insulator utilising a focused ion‐beam implantation method capable of sub‐100 nm precision. The implanted regions exhibit telecom‐band emission, with a reduction in photoluminescence intensity and lifetime below 50 K, consistent with pyroelectric‐field effects in the host ...

Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...
