Abstract
An optical cross apparatus including a single-row fiber array, and a single-row input multidimensional output optical waveguide element, where the single-row fiber array is coupled to the single-row input multidimensional output optical waveguide element, and an arbitrarily curved spatial three-dimensional waveguide is generated inside the single-row input multidimensional output optical waveguide element, and where a coupling surface of the single-row fiber array is the same as that of the single-row input multidimensional output optical waveguide element.
