Nanofiber-based high-Q microresonator for cryogenic applications

We demonstrate a cryo-compatible, fully fiber-integrated, alignment-free optical microresonator. The compatibility with low temperatures expands its possible applications to the wide field of solid-state...

Disturbing-Free Determination of Yeast Concentration in DIWater and in Glucose Using Impedance Biochips

Deionized water and glucose without yeast and with yeast (Saccharomyces cerevisiae) of optical density OD600 that ranges from 4 to 16 has been put in the ring electrode region of six different types of...

Structures for surface enhanced non-plasmonic or hybrid spectroscopy

Absorption, scattering, and fluorescence are processes that increase with electric field intensity. The most prominent way to enhance electric field intensity is to use localized or propagating surface...

Simple differentiation of Salmonella Typhi, Paratyphi, and Choleraesuis from Salmonella spp. using the eazyplex® TyphiTyper LAMP assay

Optical properties of ytterbium/aluminium doped silica glasses

Several series of preform and fiber samples of Yb2O3-Al2O3-SiO2 glass with finelygraded composition steps were prepared by MCVD and solution doping under well-defined conditions. Their optical properties,...

Real-time observation of the optical Sagnac effect in ultrafast bidirectional fibre lasers

The optical Sagnac effect sets fundamentals of the operating principle for ring laser and fiber optic gyroscopes, which are preferred instruments for inertial guidance systems, seismology, and geodesy....

Graphene and silicene quantum dots for nanomedical diagnostics

In the present work, the prominent effects of edge functionalization, size variation and base material on the structural, electronic and optical properties of diamond shaped graphene and silicene quantum...

Removing interference-based effects from infrared spectra – interference fringes re-revisited

Substantial refractive index mismatches between substrate and layers lead to undulating baselines, which are known as interference fringes. These fringes can be attributed to multiple reflections inside...

Beyond Beer’s law – why the index of refraction depends (almost) linearly on concentration

Beer’s empiric law states that absorbance is linearly proportional to the concentration. Based on electromagnetic theory, an approximately linear dependence can only be confirmed for comparably weak...

Analysis method for detecting topological defect dark matter with a global magnetometer network

The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) is a network of time-synchronized, geographically separated, optically pumped atomic magnetometers that is being used to...
