General simulation method for spontaneous parametric down- and parametric up-conversion experiments
Felix Riexinger, Mirco Kutas, Björn Haase +4
Spontaneous parametric down-conversion (SPDC) sources are an important technology for quantum sensing and imaging. We demonstrate a general simulation method, based on modeling fro…
Observation of Quadratic (Charge-2) Weyl Point Splitting in Near-Infrared Photonic Crystals
Christina Jörg, Sachin Vaidya, Jiho Noh +4
Weyl points are point degeneracies that occur in momentum space of periodic materials, and are associated with a quantized topological charge. We experimentally observe in a 3D mic…
Existence of a negative next-nearest-neighbor coupling in evanescently coupled dielectric waveguides
Julian Schulz, Christina Jörg, Georg von Freymann
We experimentally demonstrate that the next-nearest-neighbor(NNN)coupling in an array of waveguides can naturally be negative. To do so, dielectric zig-zag shaped waveguide arrays…
Observation of bound states in the continuum embedded in symmetry bandgaps
Alexander Cerjan, Christina Jörg, Sachin Vaidya +5
In the last decade, symmetry-protected bound states in the continuum (BICs) have proven to be an important design principle for creating and enhancing devices reliant upon states w…
