Mitigating effects of nonlinearities in homodyne quadrature interferometers
Johannes Lehmann, Artem Basalaev, Jonathan J. Carter +12
Homodyne Quadrature interferometers (HoQI) are an interferometric displacement sensing scheme proven to have excellent noise performance, making them a strong candidate for sensing…
Demonstrating the velocity response of a table-top EPR Speedmeter
S. L. Kranzhoff, S. L. Danilishin, S. Steinlechner +3
The sensitivity of gravitational-wave interferometers is fundamentally limited by quantum noise, as dictated by the Heisenberg uncertainty principle, due to their continuous positi…
All-polarisation beamsplitters for interferometer applications
S. L. Kranzhoff, Z. Van Ranst, J. De Bolle +9
Optical beamsplitters with similar properties for orthogonal, linear polarisation modes are required for realising polarisation-based speedmeter schemes to reduce back-action noise…
Testing Compact, Fused Silica Resonator Based Inertial Sensors in a Gravitational Wave Detector Prototype Facility
J J Carter, P Birckigt, J Lehmann +15
Future gravitational wave observatories require significant advances in all aspects of their seismic isolation; inertial sensors being a pressing example. Inertial sensors using gr…
