Recent Developments in Deep‐Ultraviolet Flat Optics
Deep‐ultraviolet flat optics (DUVFO) is emerging as a key platform for next‐generation photonics, enabling advanced functionalities beyond conventional DUV optics. This review outlines materials, devices, and system advances, highlighting wide‐bandgap platforms, while identifying key challenges in dispersion control, characterization, and wafer‐scale ...

The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Pushing the limits of deep-ultraviolet scanning near-field optical microscopy
Deep-ultraviolet (DUV) microscopy and microspectroscopy have received much attention in label-free live-cell imaging, selective molecular analysis, and optical characterizations of ultrawide bandgap materials.

Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Performance study of UV micro-LEDs with AlGaN quantum dots and transparent tunnel junction
It is well known that the size of deep ultraviolet (DUV) micro LED (μLEDs) decreases, although bandwidth improves, the optical power drops sharply, severely limiting the application of DUV μLEDs in optical communication.
