Sensitive biodetection in flow using metasurface hosting quasi-bound state in the continuum resonances
Sarah L. Walden, Anna Fedotova, Dmitry Pidgayko +4
We have designed optical metasurfaces hosting high-quality factor quasi-bound state in the continuum (q-BIC) resonances for optical biosensing in flow. The unit cell of the metasur…
Design strategies for efficient, fabrication-feasible extreme-ultraviolet metalens
Shiu Hei Lam, U Abinash Patro, Jan Rothhardt +1
The concept of metasurfaces was recently applied to the extreme ultraviolet (EUV) spectral regime, providing a new opportunity for transmissive focusing elements in a regime where…
Insights into the Nature of Quantum Emitters in Electron-Irradiated hexagonal Boron Nitride
Mouli Hazra, Anna Rupp, Mohammad N. Mishuk +10
Quantum emitters in hexagonal boron nitride (hBN) have emerged as a promising solid-state platform for quantum technology applications. However, a persistent challenge in the field…
Towards Polarization Routing of Magnetic and Electric Dipolar Emission with Dielectric Metasurfaces
Marijn Rikers, Ayesheh Bashiri, Katsuya Tanaka +4
We investigate the polarization properties of emission associated with the magnetic dipole and electric dipole transitions of europium(III) coupled to an anisotropic dielectric met…
Directional and contra-directional coupling in Huygens' metawaveguide microring resonators
M. Saad Bin-Alam, Yunus Denizhan Sirmaci, Alejandro Fernández-Hinestrosa +8
Huygens' metawaveguides represent a transformative concept in photonic device engineering, enabling unprecedented control over light propagation. This study presents, for the first…
