dc.description.abstract | When light is transmitted through the interface, it will be divided into two lights, “transmitted light” and “reflected light” respectively. The intensities of these two lights is based on the refractive index on the both sides of interface. When light is transmitted through the multilayer structure which contains countless interfaces. It makes continuously transmission and reflection in the structure. Ultimately, an infinite variety of light propagation paths are generated, and each path is one of a result. After summing all the results, the optical properties of the multilayer structure can be known.
In this study, the optical properties of the multilayer structure were calculated by Matrix Theory. First calculate the single-layer structure, and list the Wave-transfer matrix base on the refractive index and thickness of the structure. Combining several single-layer structures into multilayer structure. Because of the “multiplicative” property of the Matrix Theory, after multiplying all the single-layer matrices, the Wave-transfer matrix of the multilayer structure can be obtained.
According to the above method, the Wave-transfer matrix of any complex structure can be calculated. Combining different kind of Wave-transfer matrix to design the structure which has specific optical characteristics. Such as wideband anti-reflection film, omnidirectional reflector film, wideband filter, etc.
Finally, this research confirms that the Wave-transfer matrix can be applied to optical calculation of birefringent multilayer structure. Furthermore, the “Glass-lining folded Šolc filter” with filtering and slow light effects is designed. The positive correlation between group index, the extent of slow light and the total number of layers. It means that the above characteristics can controlled by structural design, without being limited by material. | en_US |
