Gallium phosphide on insulator for nanophotonics and quantum technologies
Tobias Bucher, Otto Arnold, Muyi Yang +7
Gallium phosphide is a promising material platform for visible and near-infrared photonics and quantum technologies owing to its high refractive index, low optical absorption, and…
Spatiotemporal Metasurface for Ultrafast All-Optical Wavefront Shaping
Mert Akturk, Giulia Crotti, Andrea Schirato +6
Optical metasurfaces have established themselves as exceptional nanophotonic platforms to control the properties of light at subwavelength scales. By properly designing the geometr…
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…
All-optical control of nonlinear emission from resonant metasurfaces
Ziwei Yang, Lei Xu, Gabriel Sanderson +11
Nonlinear optics underpins a broad range of photonic technologies, from classical and quantum light sources to emerging nonlinear photonic neural networks. Yet, conventional nonlin…
Enhancement of Circular Dichroism in Chiral Dielectric Metasurfaces by Ion Beam Irradiation
Anna Fitriana, Katsuya Tanaka, Lukas Raam Jaeger +4
Resonant chiral dielectric metasurfaces can support circular dichroism exceeding that of natural materials, but their small dissipative losses simultaneously limit the maximization…
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…
