Chiral lasing via broken parity-time symmetry in bound-state-in-the-continuum metasurfaces
Matthew Parry, Daria A. Smirnova, Andrey A. Sukhorukov +1
The paper proposes a planar metasurface design that uses spatial gain‑loss modulation to break parity‑time symmetry, enabling chiral lasing that emits nearly pure circularly polari…
Multi-wavelength polarisation imaging with inverse designed metasurfaces
Sarah E. Dean, Neuton Li, Josephine Munro +7
Multispectral polarisation imaging has a broad range of applications, from biological cell imaging to agricultural remote surveying. For such applications, especially involving lig…
Quantum Phase Gradient Imaging Using a Nonlocal Metasurface System
Jinliang Ren, Jinyong Ma, Katsuya Tanaka +4
Quantum phase imaging enables the analysis of transparent samples with thickness and refractive index variations in scenarios requiring precise measurements under low-light conditi…
Enhanced photon-pair generation from a van der Waals metasurface
Tongmiao Fan, Yilin Tang, Shaun Lung +11
Quantum photon pairs play a pivotal role in many quantum applications. Metasurfaces, two-dimensional arrays of nanostructures, have been studied intensively to enhance and control…
Enhanced Tunable Photon Pair Generation from Nonlinear Metasurface with Guided-Mode Cavity
Tongmiao Fan, Jihua Zhang, Andrey A. Sukhorukov
The ability to generate quantum entangled photon pairs through spontaneous parametric down conversion (SPDC) is playing a pivotal role in many applications in quantum technologies,…
Broadband bright biphotons from periodically poled triple-resonance metasurface
Jihua Zhang, Chaoxin Shi, Jinyong Ma +5
Biphotons from spontaneous parametric down conversion with broad bandwidth are highly wanted in many quantum technologies. However, achieving broad bandwidth in both frequency and…
