Spatial filtering of a six-wavelength DBR-RW laser in a MOPA system
/forschung/publikationen/spatial-filtering-of-a-six-wavelength-dbr-rw-laser-in-a-mopa-system
Lasing emission at multiple wavelengths can be used in different sensing applications and in optical telecommunication. In this work, we report a six-wavelength distributed Bragg reflector (DBR)…
On the Conduction Properties of Vertical GaN n-Channel Trench MISFETs
/forschung/publikationen/on-the-conduction-properties-of-vertical-gan-n-channel-trench-misfets
ON-state conductance properties of vertical GaN n-channel trench MISFETs manufactured on different GaN substrates and having different gate trench orientations are studied up to 200°C ambient…
Accurate in vivo tumor detection using plasmonic-enhanced shifted-excitation Raman difference spectroscopy (SERDS)
/forschung/publikationen/accurate-in-vivo-tumor-detection-using-plasmonic-enhanced-shifted-excitation-raman-difference-spectroscopy-serds
For the majority of cancer patients, surgery is the primary method of treatment. In these cases, accurately removing the entire tumor without harming surrounding tissue is critical; however, due to…
Ultracold atom interferometry in space
/forschung/publikationen/ultracold-atom-interferometry-in-space
Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne interferometry. Indeed, BECs enjoy a slowly expanding wave function, display a large spatial coherence and…
A 1.4 kW 780 nm pulsed diode laser, high duty cycle, passively side-cooled pump module

Influence of the hydrogen level in (InAlGa)N-based laser diodes on the stability of the device’s operating voltage
/forschung/publikationen/influence-of-the-hydrogen-level-in-inalgan-based-laser-diodes-on-the-stability-of-the-devices-operating-voltage
The impact of hydrogen impurities in the semiconductor heterostructure of (InAlGa)N-based laser diodes on the stability of the device’s operating voltage is investigated. Diodes emitting at a…
Roadmap on quantum nanotechnologies
/forschung/publikationen/roadmap-on-quantum-nanotechnologies
Quantum phenomena are typically observable at length and time scales smaller than those of our everyday experience, often involving individual particles or excitations. The past few decades have seen…
Tunable Graphene Phononic Crystal
/forschung/publikationen/tunable-graphene-phononic-crystal
In the field of phononics, periodic patterning controls vibrations and thereby the flow of heat and sound in matter. Bandgaps arising in such phononic crystals (PnCs) realize low-dissipation…
