Paper Abstract
The transmission resonances occurring in the extraordinary light transmission through metallic films with subwavelength
holes can be used to tailor the spectral transmission properties of periodic slit and hole arrays. In
this work we study with rigorous numerical simulations the corresponding changes in the coherence properties
of electromagnetic fields transmitted through periodic subwavelength metallic gratings with narrow linear slits.
Our numerical results show that by choosing suitable parameters for the grating, the degree of coherence of
the beam can be significantly increased. The studied approach offers new possibilities to alter the coherence
properties of fields using nanophotonic components.
