Abstract

Light scattering is well known to be a key limitation of the ultimate performances of filters. Whatever the values of surface roughness and bulk heterogeneity within the multilayer, the optical losses depend on the stack design and on the correlation factors between defects. Such situation is largely enhanced in the case of WDM filters, due to the high over-intensity of the electric field within the stack, as a consequence of the narrow pass-band. In this paper, we present some experimental scattering result recorded with a high angular and spectral resolution on prototype WDM filters and which illustrate the enhancement of scattering near the design wavelength of the filter.
