Step Function in Momentum Space by a Metagrating

Advanced Optical Materials, EarlyView.
This work demonstrates how the symmetry of the angular transmittance could be broken by a metagrating where the diffraction channels alleviate the requirement for enforcing absorbance. The metagrating retroreflects incident waves with positive incidence angles and transmits waves with negative incidence angles.

Development of High‐Performance Multilayer Monochromators

Advanced Optical Materials, EarlyView.
Detailed insights into the optical and multilayer design of Double Multilayer Monochromators (DMM) are presented and fully characterized, including key optimization strategies and solutions to fabrication challenges. By integrating in‐house Ion Beam Figuring and a high uniformity multilayer coating process, the developed DMMs achieve high reflectivity,

Dark‐State Guided‐Mode Resonance Sensors: Engineering Miniature Sensing Platforms

Advanced Optical Materials, EarlyView.
This research introduces compact guided‐mode resonance sensing using Gaussian‐beam‐induced symmetry breaking to excite dark states. The method generates high‐quality resonance signals in a small area, demonstrating a sensor with 128 micro‐cells and 200 nm RIU−1 sensitivity, showing potential for lab‐on‐chip and biosensing applications.

Polar Indirect Valley as a Limiting Factor for Radiative Efficiency in Gold‐Based Mixed‐Valence Double Perovskites

Advanced Optical Materials, EarlyView.
This work addresses a common issue in many double perovskites: their weak luminescence. Using the example of promising infrared‐bandgap mixed‐valence gold halide double perovskites, it demonstrates strong polar electron‐phonon coupling. Temperature‐dependent spectroscopy reveals that bright polarons are favored at low temperature, while a dark low ...

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

Advanced Optical Materials, EarlyView.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...
