Iodine Frequency Reference on a Sounding Rocket
/en/research/publications/iodine-frequency-reference-on-a-sounding-rocket
We build a self-contained optical absolute frequency reference at 1064 nm based on the rovibronic transition R(56)32-0 in molecular iodine and operate this instrument in space on a sounding…
Integrated Atomic Quantum Technologies in Demanding Environments: Development and Qualification of Miniaturized Optical Setups and Integration Technologies for UHV and Space Operation

Traveling Wave Model Based Simulation of Tunable Multi-Wavelength Diode Laser Systems
/en/research/publications/traveling-wave-model-based-simulation-of-tunable-multi-wavelength-diode-laser-systems
We show simulation results of a compact, integrated and tunable multi-wavelength diode laser emitting around 785 nm. The presented design was optimized using passive waveguide simulations and then…
Extra half-plane shortening of dislocations as an origin of tensile strain in Si-doped (Al)GaN
/en/research/publications/extra-half-plane-shortening-of-dislocations-as-an-origin-of-tensile-strain-in-si-doped-algan
Si doping of (Al,Ga)N layers grown by metalorganic chemical vapor deposition induces an inclination of threading dislocations (TDs). This inclination leads to a change of the extra half-plane size of…
