Abstract

In the present work, we fabricated model optical filters with multilayer and graded index (inhomogeneous) designs using TiO2, SiO2, and TiO2/SiO2 mixtures. The deposition process was monitored by in situ spectroscopic ellipsometry and reflectometry. The filters were further characterized by ex situ variable angle spectroscopic ellipsometry and spectrophotometry, and their compositional depth profiles were determined by elastic recoil detection in time-of-flight regime. This multitechnique approach allowed us to evaluate the effect of microstructural features on the optical performance.
