Abstract
An edge coupling method comprising positioning a first photonic device such that a first edge coupler of the first photonic device is at least partially aligned with a first alignment waveguide of a second photonic device and such that a second edge coupler of the first photonic device is at least partially aligned with a second alignment waveguide of the second photonic device, wherein the first edge coupler widens towards an edge of the first photonic device and the second edge coupler widens towards the edge, and wherein the first edge coupler and the second edge coupler are optically coupled to each other by an interconnect, transmitting a light through the first alignment waveguide, detecting the light at the second alignment waveguide, and aligning the first photonic device and the second photonic device based on the detecting.
