Abstract

Structures of nanometric scale are increasingly present in optical systems. Unfortunately, effects in the intermediate fiel of a sequence of circular apertures are little known. We investigated the effects of such structures on monochromatic and pulsed beams, and our numerical simulations predict results that could be disastrous to optical systems. For continuous waves, we calculated high intensities that could damage materials or change their index of refraction. For pulsed beams, strong pulse-shaping effects are predicted. Caution should therefore be used when designing systems containing circular apertures; diffraction effects in the near fiel should be considered.
