Metasurface optical characterization using quadriwave lateral shearing interferometry
Samira Khadir, Daniel Andrén, Ruggero Verre +5
An optical metasurface consists of a dense and usually non-uniform layer of scattering nanostructures behaving as a continuous and extremely thin optical component, with predefined…

Ultra-thin rigid endoscope: Two-photon imaging through a graded-index multi-mode fiber
Siddharth Sivankutty, Esben Ravn Andresen, Rosa Cossart +3
Rigid endoscopes like graded-index (GRIN) lenses are known tools in biological imaging, but it is conceptually difficult to miniaturize them. In this letter, we demonstrate an ultr…
