The requirements pertaining to the reliability and accuracy of micro-electromechanical gyroscopic sensors are increasing,as systems for vehicle localization emerge as an enabling f…
Spontaneous parametric down-conversion induced by optomechanical gradient forces in nanophotonic waveguides
Mohamed Ashour, Jan Niklas Caspers, Eva M. Weig +1
Optomechanical gradient forces arise from evanescent fields of guided waves in parallel photonic waveguides. When designed to be of attractive nature, they increase exponentially a…
Validating the Critical Point of Spontaneous Parametric Down-Conversion for over 600 Scanning MEMS Micro Mirrors on Wafer-Level
Ulrike Nabholz, Florian Stockmar, Jan E. Mehner +1
Sensors and actuators based on resonant micro-electro-mechanical systems (MEMS), such as scanning micro mirrors, are well-established in automotive and consumer products. As the ar…
Spontaneous parametric down-conversion induced by non-degenerate three-wave mixing in a scanning MEMS micro mirror
Ulrike Nabholz, Frank Schatz, Jan E. Mehner +1
Scanning micro-mirror actuators are silicon-based oscillatory micro-electro-mechanical systems (MEMS). They enable laser distance measurements for automotive LIDAR applications as…
Self-Consistent Projection Operator Theory in Nonlinear Quantum Optical Systems: A case study on Degenerate Optical Parametric Oscillators
Peter Degenfeld-Schonburg, Carlos Navarrete-Benlloch, Michael J. Hartmann
Nonlinear quantum optical systems are of paramount relevance for modern quantum technologies, as well as for the study of dissipative phase transitions. Their nonlinear nature make…
