| Abstract: | A novel tunable filter design which is used in DWDM system based on nematic liquid crystal, using Fabry-Perot and polarization interference effects is demonstrated. The spectrum performance of this device has been analyzed and simulated. And the change of liquid crystal refractive index with its molecular rotate angle is also described in detail. The experiment for measuring performance of device has been set up and the experimental result is coincident with the theory calculation. |
