Silicon CMOS and InGaAs(P)/InP SPADs for NIR/SWIR detection
Applications demanding imaging at low-light conditions at near-infrared (NIR) and short-wave infrared (SWIR) wavelengths, such as quantum information science, biophotonics, space imaging, and light detection and ranging (LiDAR), have accelerated the develo ...
EPFL2024Lippmann Photography: Past, Present, and Future
Paolo Prandoni, Arnaud Latty, Adrien Guillaume Olivier Hoffet, Nicoletta Isaac
The purpose of this project was to bring to a wider public an almost forgotten technique for color photography, invented by Gabriel Lippmann in 1892 and rewarded with a Nobel prize in 1908. The project was born out of a longstanding cooperation between EPF ...
2023A Highly Magnified Gravitationally Lensed Red QSO at z = 2.5 with a Significant Flux Ratio Anomaly
We present the discovery of a gravitationally lensed dust-reddened QSO at z = 2.517, identified in a survey for QSOs by infrared selection. Hubble Space Telescope imaging reveals a quadruply lensed system in a cusp configuration, with a maximum image separ ...
2023In vitro and in vivo NIR fluorescence lifetime imaging with a time-gated SPAD camera
Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü
Near-infrared (NIR) fluorescence lifetime imaging (FLI) provides a unique contrast mechanism to monitor biological parameters and molecular events in vivo. Single-photon avalanche diode (SPAD) cameras have been recently demonstrated in FLI microscopy (FLIM ...
Optica Publishing Group2022Extreme polarization-dependent supercontinuum generation in an uncladded silicon nitride waveguide
Camille Sophie Brès, Eirini Tagkoudi, Caroline Gaëlle Amiot
We experimentally demonstrate the generation of a short-wave infrared supercontinuum in an uncladded silicon nitride (Si3N4) waveguide with extreme polarization sensitivity at the pumping wavelength of 2.1 µm. The air-clad waveguide is specifically designe ...
