Roughness

OptiLayer allows evaluating the influence of small scale and large scale interface roughness on design spectral characteristics. The concept of small scale and large scale  roughness is discussed in our paper.

Scales

OptiLayer allows you to specify degrees of inhomogeneities for design layers and thicknesses of interlayers for every interface. 

Refractive index distribution throughout the layer is assumed to be linear (linearly increasing or decreasing) index profile. The degree of layer inhomogeneity is the percentage ratio of the difference between the layer refractive indices at the upper and lower layer interfaces to the mean refractive index of this layer.

Positive degree of inhomogeneity corresponds to an increasing refractive index profile. Negative degree of inhomogeneity  corresponds to a decreasing index profile. Interlayer thicknesses for each interface can be specified. 

 

InhomInter

Evaluation of scattering is possible for oblique incidence as well.

Use the Characteristic page of the Interface Roughness Setup window to set spectral characteristic for the Interface Roughness analysis. Interface Roughness analysis can be performed only for one characteristic, one polarization state and one angle of incidence at a time.

The Interface Roughness analysis option allows evaluating the influence of small scale and large scale interface roughness on the design spectral characteristics. Learn more about the concept of small scale and large scale root mean square (rms) roughness.

Scattering oblique incidence

Deviations page has been added to Roughness evaluation window. It displays the deviations of spectral characteristics caused by roughness of different kind.

Roughness Evaluation is possible without loaded design. It allows to estimate the influence of roughness of a single interface between substrate and incidence medium without additional tricks.
