Periodic Reporting for period 2 - SPEED (Speedmeter: Quantum back-action noise-free interferometry for improving the science capabilities of future gravitational wave observatories)
Periodo di rendicontazione: 2023-04-01 al 2024-09-30
This project aims at investigating a new measurement concept, so-called speedmeter, for gravitational wave detectors. If successful it will enable future gravitational wave observatories as the European Einstein Telescope to observe the Universe even further back in time towards the Big Bang.
We developed various theoretical and experimental building blocks required for exploring a practical implementation of the speedmeter concepts. This includes new simulation tools, development of a new type of optical thin-film coating as well as prrof-of-concept table top experiments.
1. Integration of polarization capabilities into the FINESSE software;
2. Development of an improved optomechanical design for squeezed light sources;
3. Development of a speedmeter inspired new quantum noise reduction scheme for gravitational wave detectors, featuring the potential benefit of not requiring kilometer long optical filter cavities.
