When Integrated Photonics Should Be Wavy
Oliver R. Müller, J. J. Erik Maris, Yannik M. Glauser +2
Increasing demand for high-performance optical devices drives the search for improved fabrication and design paradigms. While photonic circuits have traditionally used structures w…
Plasmonic Fourier Surfaces Revisited: Relating Bandgaps with Bound States in the Continuum
Alexander A. Antonov, Connor Heimig, Hannah Niese +5
Periodically corrugated metal interfaces supporting surface plasmon polaritons (SPPs) belong to the earliest nanoplasmonic platforms. Even simplest reliefs described by a few harmo…
Optical Fourier Surfaces for Free-Space Computer-Generated Holography
Y. M. Glauser, C. -Y. Shen, D. B. Seda +10
Computer-generated holography can shape electromagnetic fields by encoding wavefront information in nanostructured surfaces. However, despite significant progress, hologram designs…
Broadband, compact, and training-free optical processors for parallel image classification
Sander J. W. Vonk, Boris de Jong, Yannik M. Glauser +5
As artificial intelligence becomes increasingly prevalent, the demand for faster and more energy-efficient computing approaches grows. While optical computing offers intrinsic adva…
Fourier pixels for reciprocal light control
Yannik M. Glauser, Sander J. W. Vonk, David B. Seda +7
Digital cameras and displays utilise picture elements (pixels) that perform a single function: detecting or emitting light intensity. To exploit the full information content of ele…
Band-Edge Carrier Trapping Limits Light Emission in WSe
Juri G. Crimmann, Sander J. W. Vonk, Yannik M. Glauser +2
Monolayers of transition metal dichalcogenides (TMDs) exhibit bright photoluminescence, a desirable property for light-emitting diodes and single-photon emitters. Because the emiss…
Diffraction of Light from Optical Fourier Surfaces
Yannik M. Glauser, J. J. Erik Maris, Raphael Brechbühler +6
Diffractive surfaces shape optical wavefronts for applications in spectroscopy, high-speed communication, and imaging. The performance of these structures is primarily determined b…
High-Throughput Identification and Statistical Analysis of Atomically Thin Semiconductors
Juri G. Crimmann, Moritz N. Junker, Yannik M. Glauser +3
Transition metal dichalcogenides (TMDs) are layered two-dimensional semiconductors explored for various optoelectronic applications, ranging from light-emitting diodes to single-ph…
Spectroscopy of Single CdSe Magic-Sized Nanocrystals
Gabriel Nagamine, Julian Santen, Juri G. Crimmann +3
Chemical syntheses that provide nanocrystals (NCs) with narrow distributions in size and shape are critical for NC research. This has led to the investigation of magic-sized NCs (M…
