High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices
Advanced Optical Materials, EarlyView.A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

Visible Light Silver Nanoantenna on UV Responding Tin Nanoparticles
Advanced Optical Materials, EarlyView.EUV radiation for lithography is currently produced by a tin particle plasma, ignited by intense laser light in the infra‐red region. Here, tin nanoparticles are designed to absorb visible light with the help of a silver nanoantenna. This visible light capturing potential was confirmed by EELS and STEM, with the surface plasmon resonance of the ...

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules
Advanced Optical Materials, EarlyView.Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Advanced Optical Materials, EarlyView.Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837

Self‐Assembling Cracks to Fabricate Antireflective Antifogging Metasurfaces
Advanced Optical Materials, EarlyView.A multifunctional optical device combining antireflective and photothermal antifogging properties is developed by leveraging crack formation in colloidal films. Plasmonic nanoparticle arrays enable localized heating under illumination, while a mesoporous silica coating provides antireflection and water repellency.
