Embodiment 1
[0058] Such as figure 1 As shown, a tunable FP filter based on a lithium niobate thin film in this embodiment includes a substrate 1, a first metal layer 2, an electro-optic tunable lithium niobate thin film light-passing layer 3, and a second metal layer 4 , by controlling the voltage between the first metal layer 2 and the second metal layer 4, the central wavelength of the tunable FP filter of the present invention of the tunable filter can be adjusted.
[0059] Wherein, the substrate 1 is other high light-transmitting materials such as quartz glass or K9 glass with high light transmittance; the first metal layer 2 is placed on the substrate 1 as a lower reflection layer and an electrode layer, and the material is Al , Ag, etc., with a thickness of 10nm-30nm; the lithium niobate thin film 3 is placed on the first metal layer 2 as a half-wave resonant cavity light-passing layer, and the thickness of the lithium niobate thin film layer is λ / (2n), where λ is designed Central ...
