Two-color grating magneto-optical trap for narrow-line laser cooling
Saskia Bondza, Christian Lisdat, Stefanie Kroker +1
We demonstrate for the first time the two-color cooling and trapping of alkaline-earth atoms in a grating magneto-optical trap (gMOT). The trap is formed by a single incident laser…
Impact of Earth's gravity on Gaussian beam propagation in hemispherical cavities
Sebastian Ulbricht, Johannes Dickmann, Robert A. Müller +2
We theoretically investigate the influence of gravity on laser light in a hemispherical optical cavity, operating on Earth. The propagation of light in such a cavity is modeled by…
Thermal charge carrier driven noise in transmissive semiconductor optics
F. F. Bruns, S. P. Vyatchanin, J. Dickmann +4
Several sources of noise limit the sensitivity of current gravitational wave detectors. Currently, dominant noise sources include quantum noise and thermal Brownian noise, but futu…
Gravitational light deflection in Earth-based laser cavity experiments
Sebastian Ulbricht, Johannes Dickmann, Robert A. Müller +2
As known from Einstein's theory of general relativity, the propagation of light in the presence of a massive object is affected by gravity. In this work, we discuss whether the eff…
Modular Hybrid Plasmonic Integrated Circuit -- Rotation, Nanofocusing and Nonlinear Enhancement
Alessandro Tuniz, Oliver Bickerton, Fernando J. Diaz +5
We introduce a modular approach for efficiently interfacing photonic integrated circuits with deep-sub-wavelength hybrid plasmonic functionality. We demonstrate that an off-the-she…
Key signal contributions in photothermal deflection spectroscopy
Walter Dickmann, Johannes Dickmann, Florian Feilong Bruns +1
We report on key signal contributions in photothermal deflection spectroscopy (PDS) of semiconductors at photon energies below the bandgap energy and show how to extract the actual…
