Abstract

According to the tilted incidence characteristics of thin film narrowband interference filter, the stack of four cavities angle-tuned narrowband filter with low polarization dependent loss is designed. Using this kind fo angle-tuned thin film filter, one new structure of three-port tunable filter is developed. The experimental results show that its tunable range is at about 20nm.
