Abstract

The subject of this work is design and optical characterisation of hybrid thin film systems. The hybrid antireflective and notch designs are synthesised and compared with classical HL designs prepared with the same requirements and restrictions. Hybrid antireflective design is refined and adapted for deposition by different co-deposition methods. These coatings are deposited and their optical performance compared. Optical characterisation is performed. Origin of discrepancies between the designs and the models obtained by characterisation is related with errors in deposition processes. The model obtained using only reflectance and transmittance measurements and including ellipsometric measurements, same as the one obtained from secondary ion mass spectrometry based initial design are compared. The appropriateness of Lorentz-Lorenz model for calculation of refractive index of mixtures in optical characterisation and therefore the necessity to introduce it into designing is tested. Appropriateness of this model is related to the structure of the mixtures by additional measurements.
