Spatial mapping of intrinsic and readout nonlinearities in a strongly-driven micromechanical membrane
Timo Sommer, Agnes Zinth, Aditya +1
Recently, it was shown that strongly driven micromechanical resonators show mode shapes that strongly differ from the eigenmodes. This raises the question of the origin of this non…
3DSC - A New Dataset of Superconductors Including Crystal Structures
Timo Sommer, Roland Willa, Jörg Schmalian +1
Data-driven methods, in particular machine learning, can help to speed up the discovery of new materials by finding hidden patterns in existing data and using them to identify prom…
Graph neural networks for materials science and chemistry
Patrick Reiser, Marlen Neubert, André Eberhard +8
Machine learning plays an increasingly important role in many areas of chemistry and materials science, e.g. to predict materials properties, to accelerate simulations, to design n…
Aluminum nitride integration on silicon nitride photonic circuits: a new hybrid approach towards on-chip nonlinear optics
Giulio Terrasanta, Timo Sommer, Manuel Müller +3
Aluminum nitride (AlN) is an emerging material for integrated quantum photonics due to its large nonlinearity. Here we demonstrate the hybrid integration of AlN on silico…
Efficient optomechanical mode-shape mapping of micromechanical devices
David Hoch, Kevin-Jeremy Haas, Leopold Moller +4
We demonstrate a method to optically map multiple modes of mechanical structures simultaneously. The fast and robust method, based on a modified phase-lock-loop, is demonstrated on…
Growth of Aluminum Nitride on a Silicon Nitride Substrate for Hybrid Photonic Circuits
G. Terrasanta, M. Müller, T. Sommer +4
Aluminum nitride (AlN) is an emerging material for integrated quantum photonics with its excellent linear and nonlinear optical properties. In particular, its second-order nonlinea…
The limits for complete photonic bandgaps in low-contrast media
Lukas Maiwald, Timo Sommer, Marvin Schulz +2
The minimal refractive index contrast to obtain a complete photonic bandgap (CPBG) in structured media was not identified so far. We address this problem by considering distributed…
