OptiLayer:  Your Partner in Design and Post-Production Characterization of Optical Coatings


 Application of robust  algorithm to designing dispersive mirrors

OptiLayer allows taking into account requirement on stability of the design on errors in layer parameters. This requirement is very important for ultrafast coatings.

Example: Dispersive mirror that has to compensate GDD of -200 fs2 in the spectral range from 700 to 900 nm.

Substrate: B260 glass;

Layer Materials: Nb2O5 and SiO2.

All OptiLayer algorithms can work in the Robust mode. Absolute errors in layer thicknesses can be estimated at the \(\sigma=0.5\) nm level:

DesCol RobustSettings

Convenient design solution: 88 layers, total thickness 9273.5 nm. Excellent GDD spectral performance has been obtained:

group delay dispersion

Robust design solution: 66 layers, total thickness 9957.5 nm. Good GDD spectral performance has been achieved:

group delay dispersion

Error analysis of the convenient design solution: level of absolute thickness errors of 0.5 nm was specified.

error analysis chirp mirror

Error analysis of the robust design solution at the same level of absolute thickness errors. It is obvious, that the design is more stable.
