Toward quantum-noise-limited interferometric measurements of optical nonlinearity in vacuum
Ali Aras, Adrien E. Kraych, Xavier Sarazin +3
Quantum Electrodynamics predicts that the vacuum must behave as a nonlinear optical medium: the vacuum optical index should increase when it is stressed by intense electromagnetic…

Interferometric measurement of the deflection of light by light in air
Adrien E. Kraych, Aurélie Max Mailliet, François Couchot +8
The aim of the DeLLight (Deflection of Light by Light) experiment is to observe for the first time the optical nonlinearity in vacuum, as predicted by Quantum Electrodynamics, by m…

Performance of a Sagnac interferometer to observe vacuum optical nonlinearity
Aurélie Max Mailliet, Adrien E. Kraych, François Couchot +8
In Quantum Electrodynamics, vacuum becomes a nonlinear optical medium: its optical index should be modified in the presence of intense external electromagnetic fields. The DeLLight…
