Abstract: An optical interconnection device including: a first element layer formed on a substrate; a second element layer disposed on the first element layer and receiving an optical signal; and a mode converter interposed between the first element layer and the second element layer, and eliminating a difference between an effective refractive index of the first element layer and an effective refractive index of the second element layer and match a mode profile, wherein the first element layer, the mode converter, and the second element layer are sequentially disposed on respective planes spaced apart from each other on the substrate, and one end of the mode converter overlaps a part of the second element layer, and the other end of the mode converter overlaps a part of the first element layer.
