Designing a low-loss high reflectivity mirror for gravitational waves detectors by combining a dielectric metasurface and a multilayer stack
Edith Hartmann, Michel Lequime, Jerome Degallaix +4
The design of low-mechanical-loss, high reflectivity mirrors is crucial in the development of the next generation of gravitational-wave observatories. Currently, the amorphous mult…
Comparison of arm cavity optical losses for the two wavelengths of the Einstein Telescope gravitational wave detector
Maxime Le Jean, Jerome Degallaix, David Hofman +8
A new generation of gravitational wave detectors is currently being designed with the likely use of a different laser wavelength compared to current instruments. The estimation of…
Stable Phase Retrieval with Mirror Descent
Jean-Jacques Godeme, Jalal Fadili, Claude Amra +1
In this paper, we aim to reconstruct an n-dimensional real vector from m phaseless measurements corrupted by an additive noise. We extend the noiseless framework developed in [15],…
Low-coherence interferometric measurement of the spectral dependence of the light field backscattered by optical interfaces
Michel Lequime, Imran Khan, Myriam Zerrad +1
In this paper, we show how the combined use of low coherence interferometry, balanced detection and data processing comparable to that used in Fourier transform spectrometry allows…
Low coherence interferometric detection of the spectral dependence of the retro-reflection coefficient of an anti-reflective coated interface
Michel Lequime, Imran Khan, Myriam Zerrad +1
The measurement of very low reflection coefficients of anti-reflective coated interfaces has become a key issue for the realization of precision instruments such as the giant inter…
Provable Phase Retrieval with Mirror Descent
Jean-Jacques Godeme, Jalal Fadili, Xavier Buet +3
In this paper, we consider the problem of phase retrieval, which consists of recovering an -dimensional real vector from the magnitude of its linear measurements. We propose…
