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…
Spatio-spectrally tailored multimode metasurface lasers in the visible range
Ayesheh Bashiri, Aleksandr Vaskin, Katsuya Tanaka +3
Spectrally engineered multifrequency nanolasers are highly desirable for on-chip photonics, multiplexed biosensing, and display technologies; yet, achieving them within a single co…
Inverse-Designed Superchiral Hot Spot in Dielectric Meta-Cavity for Ultra-Compact Enantioselective Detection
Anastasia Romashkina, Omer Yesilurt, Vahagn Mkhitaryan +8
Chiral nanophotonic structures have garnered considerable interest in recent years due to their potential to enhance the efficacy of chirality-sensitive biomolecular detection. Des…
Polarization Dependent Enhancement of Magnetic Dipolar Emission with Silicon Nanodimers
Marijn Rikers, Ayesheh Bashiri, Aleksandr Vaskin +5
Eu(TTA)3 complexes are used as an emission source in the presence of high refractive index dielectric nanostructures. These nanostructures support Mie-type resonances that modify t…
