Electrically-induced resonance shifts of whispering gallery resonators made of barium magnesium fluoride
Alexander Mrokon, Heike Kraft, Dongsung Shin +4
Barium magnesium fluoride (BMF) is a ferroelectric crystal with a transparency range far beyond the one of other optical materials. In particular, its low loss in the deep ultravio…
High-sensitivity quantum sensing with pump-enhanced spontaneous parametric down-conversion
Chiara Lindner, Jachin Kunz, Simon J. Herr +3
Recent years have seen the development of quantum sensing concepts utilizing nonlinear interferometers based on correlated photon pairs generated by spontaneous parametric down-con…
Electro-optically tunable single-frequency lasing from neodymium-doped lithium niobate microresonators
Yannick Minet, Simon J. Herr, Ingo Breunig +2
Tunable light sources are a key enabling technology for many applications such as ranging, spectroscopy, optical coherence tomography, digital imaging and interferometry. For minia…
Electro-optic eigenfrequency tuning of potassium tantalate-niobate microresonators
Jan Szabados, Christoph S. Werner, Simon J. Herr +2
Eigenfrequency tuning in microresonators is useful for a range of applications including frequency-agile optical filters and tunable optical frequency converters. In most of these…
Frequency comb up- and down-conversion in a synchronously-driven optical microresonator
Simon J. Herr, Victor Brasch, Jan Szabados +6
Optical frequency combs are key to optical precision measurements. While most frequency combs operate in the near-infrared regime, many applications require combs at mid-infrared,…
Quasi-phase-matched nonlinear optical frequency conversion in on-chip whispering galleries
Richard Wolf, Yuechen Jia, Sebastian Bonaus +5
Chip-integrated whispering-gallery resonators enable compact and wavelength-agile nonlinear optical frequency synthesizers. So far, the most flexible phase-matching technique, i.e.…
Giant and accessible conductivity of charged domain walls in lithium niobate
Christoph S. Werner, Simon J. Herr, Karsten Buse +4
Ferroelectric domain walls are nm-sized interfaces between sections of different allowed values of the spontaneous polarization, the so-called domains. These walls - neutral or cha…
