Abnormal Unidirectional Lasing from the Combined Effect of non‐Hermitian Modulated Bound States in the Continuum and Fabry–Pérot Resonance

Laser &Photonics Reviews, Volume 19, Issue 7, April 4, 2025.
A parity‐time (PT) symmetry grating results in an asymmetric split of bound states in the continuum (BIC). Based on the joint effect of the asymmetric PT‐BICs and cavity resonance, a line source produces unidirectional and single mode lasing with an interesting wavefront transformation: from a diverging wave to a unidirectional plane wave.

3D Terahertz Confocal Imaging with Chromatic Metasurface

Laser &Photonics Reviews, Volume 19, Issue 7, April 4, 2025.
A passive terahertz focusing metasurface is designed to achieve frequency‐dependent focal lengths while maintaining a constant spot size. It enables 3D see‐through non‐metallic objects with fixed spatial resolution across a large depth‐of‐field. The proposed metasurface can be employed in various applications, including in‐situ defect detection, object

Maskless Synthesis of van der Waals Heterostructure Arrays Engineered for Light Harvesting on Large Area Templates

Small, Volume 21, Issue 15, April 16, 2025.
Large area fabrication of few‐layer MoS2‐WS2 vertical heterostructures nanoarrays over periodically nanostructured silica templates is demonstrated by means of a custom‐made physical deposition set‐up. The optical anomalies arising from subwavelength periodicity and the engraved WS2 nanostripes acting as optical sensitizers result in broadband and ...
