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.Claims:
