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…
