The Refractive Index of Gallium Antimonide
Ulrich Galander, Nicolas Huwyler, Mirela Encheva +2
Gallium antimonide (GaSb) is a key material for near- and mid-infrared photonics, enabling high-performance laser architectures and detectors. Design and simulation of such devices…
Broadband birefringence spectroscopy with sub-kHz precision
Maximilian Prinz, Dominik Charczun, Marcin Bober +5
Although current amorphous high-reflective mirror coatings have had tremendous success in metrology applications, they are inherently limited by thermal fluctuations in their coati…
The R-index: A universal metric for evaluating OAM content and mode purity in optical fields
Monika Bahl, Georgios M. Koutentakis, Mikhail Maslov +4
Despite its pivotal role in optical manipulation, high-capacity communications, and quantum information, a general measure of orbital angular momentum (OAM) in structured light rem…
Group Delay Dispersion Measurements of Novel Multilayer Interference Coatings in the Mid-Infrared Spectral Regime
Ulrich Galander, Maximilian Prinz, Lukas W. Perner +1
We present the methods and results for broadband group delay dispersion measurements for all-monocrystalline and amorphous-crystalline hybrid supermirrors, as well as an all-amorph…
