Abstract
For a 100 GHz DWDM angle-tuned filter with low polarization dependent loss, the insertion loss and the Gaussian-transformation tendency of the transmission spectrum will become more serious as the incident angle is increased. It is because of that the optical path and the transmission modes of the thin film filter will change when the incident angle is varied. According to the thin film matrix theory, the analysis model is established, the displacement change of the transmission field is simulated, and a dynamic compensation fitting is also designed and fabricated in the paper. The experimental results show that it can effectively reduce the insertion loss and the phenomenon of Gaussian process. Using the compensation fitting, the tunable range of the filter is at about 20 nm which coincides with the theoretical design.
