Advanced Optical Materials, Volume 13, Issue 29, October 13, 2025.Polaritons, or hybridized excitations of light and matter, have been recently discovered in high‐quality freestanding oxide membranes of perovskite oxides like SrTiO3 grown by hybrid molecular beam epitaxy. This work finds that hybridization of polaritons across membrane interfaces produces waves with simultaneously tunable positive and negative group ...

Advanced Optical Materials, Volume 13, Issue 29, October 13, 2025.The nanoparticle‐on‐slit (NPoS) cavity has emerged as a sub‐wavelength platform for efficient coherent frequency conversion between mid‐infrared and visible light, and for nanoscale nonlinear vibrational spectroscopy. This numerical study identifies the NPoS quasi‐normal modes, relates them to known nanogap patterns, and predicts the relative ...

Advanced Optical Materials, Volume 13, Issue 28, October 2, 2025.High‐performance narrowband NIR organic photodiodes are essential for miniaturized imaging, sensing, and wearable systems, yet existing approaches suffer from angular sensitivity and limited material compatibility. This work demonstrates the first polariton‐enhanced OPDs with angle‐independent response, sub‐45 nm bandwidth, and record responsivity (0 ...

Advanced Optical Materials, Volume 13, Issue 30, October 24, 2025.TiN epilayers grown by molecular‐beam epitaxy offer reflectivity comparable to Au films but with superior thermal stability. When coupled with InSe, the InSe/TiN heterostructure exhibits remarkable enhancements in both photoluminescence and second‐harmonic generation compared to SiO2.

Interparticle Distance Controls Ultrafast Photodynamics in Crystalline Gold Superstructures
Advanced Optical Materials, Volume 13, Issue 30, October 24, 2025.Densely packed, crystalline gold superparticles with tunable interparticle distances are employed as a model system to study the effects of cross‐talk between nanoparticles on the ultrafast carrier dynamics via a combination of advanced experimental techniques and numerical simulations.
