140 µm single-polarization passive fully aperiodic-large pitch fibers operating near 2 µm
In this paper the authors demonstrate a single-polarization feature out of passive very large mode area fully-aperiodic large pitch fibers. It has been previously shown theoretically that one of the two...
PublikationenThree-dimensional holographic optical manipulation through a high-numerical-aperture soft-glass multimode fibre
Holographic optical tweezers (HOT) holds great promise for many applications in modern biophotonics, allowing the creation and measurement of minuscule forces on biomolecules, molecular motors and cells....
PublikationenNon-invasive characterization of optical fibers
Capillary optical fibers with hole diameters of several micrometers are important for novel plasmonic applications and medical diagnosis. In order to ensure the optical functionality of these fibers, the...
PublikationenIndependently tunable dual-wavelength fiber oscillator with synchronized pulsed emission based on a theta ring cavity and a fiber Bragg grating array
We present a fiber-integrated laser enabling independent tuning of two emission wavelengths with synchronized pulsed emission. The discrete tuning concept comprises a theta cavity fiber laser (TCFL), a...
PublikationenMonolithic optofluidic mode coupler for broadband thermo- and piezo-optical characterization of liquids
We present a monolithic fiber device that enables investigation of the thermo- and piezo-optical properties of liquids using straightforward broadband transmission measurements. The device is a directional...
PublikationenFlux trapping in multi-loop SQUIDs and its impact on SQUID-based absolute magnetometry
The effect of flux trapping on the flux-voltage characteristics of multi-loop SQUID magnetometers was investigated by means of repeated cool-down cycles in a stepwise increased magnetic background field....
PublikationenSize Matters: Cocatalyst Size Effect on Charge Transfer and Photocatalytic Activity
Hybrid semiconductor-metallic nanostructures play important role in a wide range of applications, and are key components in photocatalysis. Here we reveal that the nature of a nano-junction formed between...
PublikationenSwitching dynamics of an underdamped Josephson junction coupled to a microwave cavity
Current biased Josephson junctions are promising candidates for the detection of single photons in the microwave frequency domain. With modern fabrication technologies the switching properties of the junction...
PublikationenAn artificial photosynthetic system for photoaccumulation of two electrons on a fused dipyridophenazine (dppz) – pyridoquinolinone ligand
Increasing the efficiency of molecular artificial photosynthetic systems is mandatory for the construction of functional devices for solar fuels production. Decoupling the light-induced charge separation...
PublikationenOptical Assets of In situ Electro-assembled Platinum Black Nanolayers
Optoelectronic technology has been increasingly driven towards miniaturization. In this regard, maintaining the optical properties of the bulk materials while reducing their size is a critical need. How...
