Scattering in Single-and Twin-Cavity Narrow-Band Interference Filters Illuminated by a Monochromatic Light
The scattering behaviors of all-dielectric single-and twin-cavity narrow-band interference filters are studied both in theory and inexperiment. It is shown that the scattering properties are determined mainly by the spacers in which the electric field intensitites are high because of the pressence of high standing-wave fields. The scattered light cones are found in both sides of the filters illuminated by a monochromatic light with shorter wavelength than the peak wavelength of the filter. The scattering angle of each cone is equal to the tilted angle of the filter when the peak wavelength of the filter shifts to that of incident light. The calculations are in good agreement with experimental results.
