All-dielectric metasurface polarization scrambler for imaging applications
Edith Hartmann, Michel Lequime, Matthieu Castelnau +2
Polarization scramblers are essential for many imaging applications involving polarization sensitive instruments and partially polarized fluxes. In such cases, the light must be de…
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…
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…
Anomalous refraction phenomena in a transparent slab
Michel Lequime, Claude Amra
An exact formulation of the propagation of a monochromatic wave packet impinging upon a transparent, homogeneous, isotropic and parallel slab at oblique incidence is presented. App…
Optical scatter of quantum noise filter cavity optics
Daniel Vander-Hyde, Claude Amra, Michel Lequime +3
Optical cavities to filter squeezed light for quantum noise reduction require optics with very low scattering losses. We report on measured light scattering from two super-polished…
Phase retrieval of reflection and transmission coefficients from Kramers-Kronig relations
Boris Gralak, Michel Lequime, Myriam Zerrad +1
Analytic and passivity properties of reflection and transmission coefficients of thin-film multilayered stacks are investigated. Using a rigorous formalism based on the inverse Hel…
Optical properties of multilayer optics including negative index materials
Michel Lequime, Boris Gralak, Sebastien Guenneau +2
Negative indices are revisited through the thin-film admittance formalism. Effective indices and phase delay associated with wave propagation through negative index layers are care…
Negative Index Materials: The Key to "White" Multilayer Fabry-Perot
Michel Lequime, Boris Gralak, Sebastien Guenneau +2
The use of negative index materials is highly efficient for tayloring the spectral dispersion properties of a quarter-wavelength Bragg mirror and for obtaining a resonant behavior…
