Phase amplitude coupling in spectral phase modulation

摘要

We report the experimental study of spatio-temporal coupling innspectral phase modulation. Spectral phase modulation relies on thencreation of a Fourier plane where spectral components are dispersed andnindependently focused on a modulator, which allows to locally change thenoptical path. Spatio-temporal coupling arising from the principle ofnspectral phase modulation in itself has been experimentally studied fornvarious typical phase modulations and compared to simulations
