Engineering Absorption for Foil Applications
Light matter interactions such as extinction, reflection, and transmission can be described by classical optics. Dur-ing the past decades, research focused on a novel resonant extinction type called plasmonics that allows for en-hancement of both types of ...
EPFL2022Roadmap on multimode light shaping
Tobias Kippenberg, Jérôme Faist, Marco Piccardo
Our ability to generate new distributions of light has been remarkably enhanced in recent years. At the most fundamental level, these light patterns are obtained by ingeniously combining different electromagnetic modes. Interestingly, the modal superpositi ...
IOP Publishing Ltd2022Alertness in work environments - on the role of indoor daylight exposure
Light enables to see the world around us, while playing a key role in our biological functioning. During the last decades, light has become an important research topic for chronobiologists and neuroscientists, and their findings are increasingly interwoven ...
EPFL2021Image-Based Acquisition and Modeling of Polarimetric Reflectance
Wenzel Alban Jakob, Tizian Lucien Zeltner, Xin Tong
Realistic modeling of the bidirectional reflectance distribution function (BRDF) of scene objects is a vital prerequisite for any type of physically based rendering. In the last decades, the availability of databases containing real-world material measurem ...
ASSOC COMPUTING MACHINERY2020Photovoltaic organic interface for neuronal stimulation in the near-infrared
Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Laura Ferlauto, Naïg Aurelia Ludmilla Chenais, Elodie Geneviève Zollinger
Organic materials, such as conjugated polymers, are attractive building blocks for bioelectronic interfaces. In particular, organic semiconductors show excellent performance in light-mediated excitation and silencing of neuronal cells and tissues. However, ...
2020Colorimetry of Luminescent Lanthanide Complexes
Anne-Sophie Chauvin, Julien Alexandre Andres
Europium, terbium, dysprosium, and samarium are the main trivalent lanthanide ions emitting in the visible spectrum. In this work, the potential of these ions for colorimetric applications and colour reproduction was studied. The conversion of spectral dat ...
MDPI2020Multichromatic calibration method and device
A Multichromatic Calibration (MC) method of at least a spectral sensor which is one of a list comprising at least a spectrometer, a multispectral sensor, a hyperspectral sensor, a spectral camera, a color camera. The method comprises a. generating a plural ...
2019Ultrabroadband 3D invisibility with fast-light cloaks
Hatice Altug, Dordaneh Etezadi, Kosmas Tsakmakidis, Ershad Mohammadi, Foziyeh Sohrabi
An invisibility cloak should completely hide an object from an observer, ideally across the visible spectrum and for all angles of incidence and polarizations of light, in three dimensions. However, until now, all such devices have been limited to either s ...
