197 nm femtosecond laser-pulse duration: comparison of autocorrelation measurements
An easy and reliable way is presented to measure the duration of UV femtosecond laser pulses of t < 200 nm. The used autocorrelation techniques are based on two photon absorption (TPA) in different...
PublikationenSQUID-based setup for the absolute measurement of the Earth’s magnetic field
We present a configuration of LTS dc SQUID magnetometers that is capable to measure the absolute values of the vector components of the Earth’s magnetic field with a white noise level of about 6 fT/Hz1/2....
PublikationenEnhancing Chemical and Optical Stability of Silver Nanostructures by Low-Temperature Hydrogen Atoms Processing
A large variety of applications ranging from plasmonic sensing to plasmonic enhanced solar cells, photonics and optics can benefit from a reliable method to enhance chemical and time stability of silver...
PublikationenA new high detectivity room temperature linear thermopile array with a D* greater than 2 x 10^9 cmHz1/2/W based on organic membranes
We present a newly designed high detective thermoelectric linear array based on an organic membrane for the room temperature range. The sensor array has 64 individual readable channels and was designed...
PublikationenOperation of Low-Tc Circuits in a Magnetic Environment
Low-Tc Rapid Single Flux Quantum (RSFQ) digital circuits without magnetic shielding fabricated with the FLUXONICS Foundry have been studied in presence of external magnetic fields. Magnetic fields parallel...
PublikationenSFQ Circuits with Ground Plane Hole-Assisted Inductive Coupling Designed with InductEx
The design of single flux-quantum (SFQ) circuits requires well-defined inductances. In many cases these are created by irregular geometries and a computer aided design tool is necessary for inductance...
PublikationenMathematical analysis of multiplexing techniques for SNSPD arrays
Superconducting single photon detectors (SNSPD) are distinguished by a very high sensitivity, a broad spectral range and a sparse dark count rate. Therefore, arrays of SNSPDs enable novel ultra sensitive...
PublikationenPlasmonic Coupling and Long-Range Transfer of an Excitation along a DNA Nanowire
We demonstrate an excitation transfer along a fluorescently labeled dsDNA nanowire over a length of several micrometers. Launching of the excitation is done by exciting the localized surface plasmon mode...
PublikationenModeling of noise-induced jitter in low-power mixed-signal circuits using a high-level description
This work describes the high-level modeling of the effects of noise for performance analyses in circuits and systems which are prone to statistical errors. In order to allow for comprehensive studies,...
PublikationenGeneration of volume Bragg gratings by 400 nm femtosecond laser pulses with Talbot-type interferometer in S-TIH53 glass
Volume Bragg gratings were inscribed in the non-photosensitive glass material S-TIH53 from OHARA using a fs laser system and a Talbot interferometer. We demonstrate the basic applicability of our technique...
