A digital twin for a chiral sensing platform
Markus Nyman, Xavier Garcia-Santiago, Marjan Krstić +7
Nanophotonic concepts can improve many measurement techniques by enhancing and tailoring the light-matter interaction. However, the optical response of devices that implement such…
On enhanced sensing of chiral molecules in optical cavities
Philip Scott, Xavier Garcia-Santiago, Dominik Beutel +3
The differential response of chiral molecules to incident left- and right- handed circularly polarized light is used for sensing the handedness of molecules. Currently, significant…
Bayesian optimization with improved scalability and derivative information for efficient design of nanophotonic structures
Xavier Garcia-Santiago, Sven Burger, Carsten Rockstuhl +1
We propose the combination of forward shape derivatives and the use of an iterative inversion scheme for Bayesian optimization to find optimal designs of nanophotonic devices. This…
Measuring the electromagnetic chirality of 2D arrays under normal illumination
X. Garcia-Santiago, S. Burger, C. Rockstuhl +1
We present an electromagnetic chirality measure for 2D arrays of subwavelength periodicities under normal illumination. The calculation of the measure uses only the complex reflect…
Helicity-preserving optical cavity modes for enhanced sensing of chiral molecules
Joshua Feis, Dominik Beutel, Julian Köpfler +4
Researchers routinely sense molecules by their infrared vibrational "fingerprint" absorption resonances. In addition, the dominant handedness of chiral molecules can be detected by…
Achiral, Helicity Preserving, and Resonant Structures for Enhanced Sensing of Chiral Molecules
Florian Graf, Joshua Feis, Xavier Garcia-Santiago +3
We derive a set of design requirements that lead to structures suitable for molecular circular dichroism (CD) enhancement. Achirality of the structure and two suitably selected seq…
