Abstract

Manipulation of both temporal and spatial electromagnetic coherence with thin, deterministic elements is discussed. It is first shown that guided-mode resonance in diffraction gratings may lead to strong depolarization of light even if the light is quasi-monochromatic. A similar phenomenon is then shown to lead spatially variant depolarization in the space– frequency domain: Partial spatial coherence and transverse field shifts due to the resonance condition lead to decrease of the correlation between the two polarization components.
