Interferometer to measure temperature-dependent angular tilts and mode matching of fiber couplers — •Juliane von Wrangel — Max-Planck-Institut für Gravitationsphysik Hannover (Albert-Einstein-Institut)

Space-based laser interferometers as the Laser Interferometer Space Antenna (LISA) bear the challenge of developing qualified optical components that have to meet several requirements. One of the most important aspects to be considered is thermal stability: Thermally induced tilts of the components can easily couple to changes in the optical pathlength.

This poster explains an interferometer that was constructed to measure temperature-dependent angular tilts and mode matching of fiber couplers. Differential Wavefront Sensing as well as Differential Power Sensing will be used to investigate the thermal stability of commercial fiber couplers.
