Quasi-monolithic Interferometer for the Examination of the fundamental Non-reciprocity of a single-mode polarization maintaining Fiber for LISA
Abstract
The Laser Interferometer Space Antenna (LISA) mission requires optical fibers for the exchange of light between optical benches on satellites. Currently, the first prototype of these optical benches is being built for the European Space Agengy (ESA). One of the pre-experiments for the this process is to test the reciprocity of fibers. √ The non-reciprocal length noise of these fibers may not exceed 1 pm/ Hz. A quasi-monolithic, interferometric measurement setup was developed to measure these small non-reciprocal vari-ations. The measurement principle of this setup resembles the actual application on board LISA. We give an overview over current results of the measurement sensitivity of our setup and of non-reciprocal fiber noise measured using this setup. Furthermore, we will discuss noise sources that were identified and present solutions for their mitigation.
