Tatiana Amochkina, Michael Trubetskov, Petar Pervan, Vesna Janicki, Smart Color Designs with Ag and Au Metal-Island Films

We design multilayer structures incorporating silver and gold metal-island films in two different embedding materials SiO₂ and Y₂O₃ to achieve the reflectance of three distinct colors. The designs are specially adjusted for micro and nanoarray fabrication to involve the least number of deposition runs. The designs shown in the picture are obtained using one synthesis run using a sophisticated combination of algorithms and features of OTF Studio software.

Tatiana Amochkina, Alexander Myslivets, Nadzeya Khinevich, Jordi Sancho-Parramon, Vesna Janicki, Michael Trubetskov, Characterization of PARMS Produced 1-µm thick Ta₂O₅ and SiO₂ Monolayers in 0.35-5 µm Spectral Range

Layer materials Ta₂O₅ and SiO₂ are widely used for production of optical coatings in the broadband spectral ranges. Optical properties of PARMS produced monolayers were characterized based on spectral and ellipsometric data using two software tools. Layer thicknesses on the Fused Silica and Si substrates are different. It was assumed that the reson is different thermal behaviour of two substrate. It was very interesting to discuss at the poster session.

Tatiana Amochkina, Vladislav Matusevich, Jordi Sancho-Parramon, Michael Trubetskov, Reliable Characterization of SK-1300, MgF2, ZnSe, and Si Substrates in 0.2-4.2 µm Spectral Range

Precise knowledge of substrate optical properties is essential for the theoretical design and monitoring of optical coatings, layer characterization, and reverse engineering of fabricated multilayers. We demonstrate a reliable method for substrate characterization.
