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…
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…
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…
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…
Compact, all-PM fiber integrated and alignment-free ultrafast Yb:fiber NALM laser with sub-femtosecond timing jitter
Yuxuan Ma, Sarper H. Salman, Chen Li +8
We report a simple and compact design of a dispersion compensated mode-locked Yb:fiber oscillator based on a nonlinear amplifying loop mirror (NALM). The fully polarization maintai…
Mid-infrared monocrystalline interference coatings with excess optical loss below 10 ppm
G. Winkler, L. W. Perner, G. -W. Truong +13
We present high-reflectivity substrate-transferred single-crystal GaAs/AlGaAs interference coatings at a center wavelength of 4.54 um with record-low excess optical loss below 10 p…
