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…
Role of Geometric Shape in Chiral Optics
Philipp Gutsche, Xavier Garcia-Santiago, Philipp-Immanuel Schneider +3
The distinction of chiral and mirror symmetric objects is straightforward from a geometrical point of view. Since the biological as well as the optical activity of molecules strong…
Decomposition of scattered electromagnetic fields into vector spherical wave functions on surfaces with general shapes
Xavier Garcia-Santiago, Martin Hammerschmidt, Sven Burger +3
Decomposing the field scattered by an object into vector spherical harmonics (VSH) is the prime task when discussing its optical properties on more analytical grounds. Thus far, it…
