Advancing All‐Day Passive Radiative Cooling Performance of 3D Anodized Aluminum Oxide Nanostructures on Aluminium

open access: yesAdvanced Optical Materials, EarlyView.
Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...

Fabrication and Optical Characterization of CMOS‐Compatible Honeycomb‐Like Large‐Scale Lattices of Near‐Field Coupled Plasmonic TiN Nanotriangles

open access: yesAdvanced Optical Materials, EarlyView.
Honeycomb‐like plasmonic titanium nitride nanotriangle arrays are fabricated in a complementary metal‐oxide‐semiconductor pilot line. Experimental and simulated reflectances as a function of energy and in‐plane momentum match a dispersion relation based on nearest‐neighbor dipole coupling, this indicates Diract points at the K point.

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

open access: yesAdvanced 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 ...

Revealing the True Nature of Double‐Peak Emission in 2D Perovskite Single Crystals Using Polariton Waveguides

open access: yesAdvanced Optical Materials, EarlyView.
Engineering structural distortion in Dion–Jacobson perovskites allows control over optical properties and electronic band structure, unveiling new structure‐property insights. Crystal microwires act as waveguides with strong light‐matter coupling, explaining the double peak emission.
