Zusammenfassung:•A convenient method for producing 3D photonic structures was experimentally demonstrated.•This method utilizes a cutting-combination lens to generate multi-beam interference.•This method has good flexibility and scalability, and has high production efficiency.•This method is suitable for making periodic and quasi-periodic 3D microstructures. A convenient method for producing three-dimensional photonic lattice microstructures was experimentally demonstrated by using a cutting-combination lens. Three-dimensional photonic lattices are optically induced by (4 + 1) plane waves interference in an iron-doped lithium niobate photorefractive crystal. Induced three-dimensional lattice microstructures are observed and verified by planar guided wave intensity imaging and far-field diffraction pattern. This method is inexpensive and does not require complex adjustment devices. In addition, it also has flexibility and scalability. This method can be used to fabricate other more complex three-dimensional photonic lattice microstructures by designing the cutting-combination lens appropriately.
