Adaptively mixed thin films for advanced optical coatings with reduced stress and tunable refractive index.

ABSTRACT: A wide variety of optical components are used in optical instruments such as laser devices, spectrophotometers, cameras and telescopes. To enhance their performance, these components are often coated with optical thin films including antireflection (AR) coatings, high reflection (HR) coatings, polarizing films, translucent films, and bandpass filters. However, the fabrication of multilayer thin-film coatings is often constrained by stresses that arise during the deposition process. These stresses can lead to delamination, thereby limiting the range of dielectric materials and operating wavelengths available for optical components. We report a novel thin-film fabrication method that enables both refractive index control and significant stress reduction. This approach produces adaptively mix
