Some applications of thin film coatings include waveguides, ┉ ┉ anti-reflective(AR) coatings or high reflectivity(HR) coatings for use in precision 封 ┉ optics, LEDs and lasers. Generally the film compositions, as well as layer structure and 业 ┉ thickness must be precisely defined in order to provide the desired optical property. 专 ┉ ┉ Design multilayer film structured materials composed of alternating layers of ┉ SiO2 and TiO2 used for AR coatings and HR coatings, respectively. ┉ ┉
