Embodiment Construction
[0014] The periodic polarization inverted lithium niobate optical waveguide suitable for all-optical signal processing according to the present invention includes a waveguide layer 1, a substrate 2, an upper photonic crystal 3 and a lower photonic crystal 4, and the lower photonic crystal 4 is grown on the substrate 2 , directly bond it with the waveguide layer 1 , and grow the photonic crystal 3 on the waveguide layer 1 . Wherein the upper photonic crystal 3 and the lower photonic crystal 4 can be the same structure, also can be different structures, they can be one-dimensional photonic crystal (such as figure 1 shown), two-dimensional photonic crystals (such as figure 2 As shown, it is prepared by punching holes at the upper and lower ends of the waveguide layer or by other means) or a three-dimensional photonic crystal.
[0015] The present invention needs to design the structure of the upper photonic crystal 3 and the lower photonic crystal 4 (i.e. high and low refractiv...
