Simultaneous Measurement of Mid-Infrared Refractive Indices in Thin-Film Heterostructures: Methodology and Results for GaAs/AlGaAs
Lukas W. Perner, Gar-Wing Truong, David Follman +5
We present our results for simultaneous measurement of the refractive indices of gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs) from $2.…
MAQRO -- BPS 2023 Research Campaign Whitepaper
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +43
The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations…
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…
Direct Frequency Comb Measurement of OD + CO -> DOCO Kinetics
Bryce J. Bjork, Thinh Q. Bui, Oliver H. Heckl +9
The kinetics of the OH + CO reaction, fundamental to both atmospheric and combustion chemistry, are complex due to the formation of the HOCO intermediate. Despite extensive studies…
Tensile strained membranes for cavity optomechanics
G. D. Cole, P. -L. Yu, C. Gärtner +8
We investigate the optomechanical properties of tensile-strained ternary InGaP nanomembranes grown on GaAs. This material system combines the benefits of highly strained membranes…
Cooling-by-measurement and mechanical state tomography via pulsed optomechanics
M. R. Vanner, J. Hofer, G. D. Cole +1
Observing a physical quantity without disturbing it is a key capability for the control of individual quantum systems. Such back-action-evading or quantum-non-demolition measuremen…
