Abstract
According to embodiments of the present invention, an optical coupling device is provided. The optical coupling device includes a substrate, and a grating arrangement including a plurality of grating elements, the plurality of grating elements being defined on one surface of the substrate, wherein the plurality of grating elements are arranged to have a first period along a first direction, and a second period along a second direction orthogonal to the first direction, the first period being different from the second period. According to further embodiments of the present invention, a photonic integrated circuit and a method of forming an optical coupling device are also provided.
