Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials
Advanced Materials Technologies, EarlyView.This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Femtosecond laser written waveguides in sapphire for visible light delivery [PDF]
arXivA promising solution for scalable integrated optics of trapped-ion quantum processors are curved waveguides guiding visible light within sapphire bulk material. To the best of our knowledge, no curved waveguides were investigated in sapphire so far, and no measurements of waveguides with visible light in undoped planar sapphire substrates were reported.

Hybrid Electroluminescence Device for On‐Demand Single Photon Generation at Room Temperature
Advanced Optical Materials, EarlyView.New type of electroluminescent device based on hBN nanocrystals deposited on a GaN laser diode displays electrically driven emission of single photons at room temperature. Low g2(0) autocorrelation function values are achieved of < 0.2 for continuous driving and < 0.4 for on‐demand single‐photon emission.
