Unveiling nanolaser physics: Non-Perturbative Measurement of the Lasing-Mode Photon Population at the Sub-Picoseconds and Nanometer Scale
Cléo Santini, Thi Huong Ngo, Luiz H. G. Tizei +13
Semiconducting nanowire lasers (NWLs) constitute nanometer-scale modular and tunable light sources hence an essential component for integrated opto-electronics. However, improving…

Morphologies of caustics studied by catastrophe charged-particle optics
Tom Fraysse, Robin Cours, Hugo Lourenço-Martins +1
This paper explores the topologies of caustics observed in instruments that employ charged particles, such as electron and ion microscopes. These geometrical figures are studied he…
