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…
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…
Second-harmonic generation for enhancing the performance of diffractive neural networks
Marie Braasch, Anna Kartashova, Elena Goi +2
Diffractive neural networks (DNNs) are an emerging approach for the realization of photonic artificial intelligence, especially due to their suitability for machine-vision applicat…
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…
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…
