Fiber-interfaced hollow-core light cage: a platform for on-fiber-integrated waveguides
Here, we demonstrate the realization of hollow-core light cages (LCs) on commercial step-index fibers using 3D nanoprinting, resulting in fully fiber-integrated devices. Two different light cage geometries...
PublicationsEffects and avoidance of photoconversion-induced artifacts in confocal and STED microscopy
Fluorescence microscopy is limited by photoconversion due to continuous illumination, which results in not only photobleaching but also conversion of fluorescent molecules into species of different spectral...
PublicationsMicro-optical elements from optical-quality ZIF-62 hybrid glasses by hot imprinting
Hybrid glasses derived from meltable metal-organic frameworks (MOFs) promise to combine the intriguing properties of MOFs with the universal processing ability of glasses. However, the shaping of hybrid...
PublicationsRaman spectral analysis in the CHx-stretching region as a guiding beacon for non-targeted, disruption-free monitoring of germination and biofilm formation in the green seaweed Ulva
Raman spectroscopy was used to study the complex interactions and morphogenesis of the green seaweed Ulva (Chlorophyta) and its associated bacteria under controlled conditions in a reductionist model system....
PublicationsAll-fiber fast acousto-optic temporal control of tunable optical pulses
We demonstrate a new all-fiber electrically tunable modulation method which significantly reduces the response time of a Bragg grating acousto-optic modulator. A 4 cm long device is fabricated with a 1...
PublicationsDesign dependence of noise in Nb-based dc SQUIDs
Noise in superconducting quantum interference devices (dc SQUIDs) with different design, based on Nb/AlOx/Nb technology, has been systematically measured at temperature T = 4.2 K. We demonstrate that for...
PublicationsProspects for memristors with hysteretic memristance as so-far missing core hardware element for transfer-less data computing and storage
We like and need Information and Communication Technologies (ICTs) for data processing. This is measurable in the exponential growth of data processed by ICT, e.g., ICT for cryptocurrency mining and search...
PublicationsDOX-DNA Interactions on the Nanoscale: In Situ Studies Using TipEnhanced Raman Scattering
Chemotherapeutic anthracyclines, like doxorubicin (DOX), are drugs endowed with cytostatic activity and are widely used in antitumor therapy. Their molecular mechanism of action involves the formation...
PublicationsA Real-Time LSPR-Based Study of Metal-Organic Framework(MOF) Growth
MOFs are known for their absorption properties and widely used for accumulation, filtering, sensorics, photothermal, catalytical and other applications. Their combination with plasmonic metal nanoparticles...
PublicationsPhotonic data analysis in 2050
Photonic data analysis is a field at the intersection of imaging, spectroscopy, machine learning, and computer science. The diversity of both data types and application scenarios requires flexibility in...
