Phase amplitude coupling in spectral phase modulation

摘要

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