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…
Profiling THz Beams With Off-Label Use of Infrared Microbolometric Cameras
Gabriel Nagamine, Carlo Vicario, Tariq Leinen +6
Visualizing the spatial profile of light beams is essential for evaluating irradiance, characterizing beam quality, and achieving precise alignment. In the optical spectral range,…
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…
