Abstract: An optical coupler for forming an optical connection between one or more two dimensional photonic array devices and an optical fiber and for forming an electrical connection between the two dimensional photonic array devices and a substrate, a system including the optical coupler and materials, and methods of forming the optical coupler and system are disclosed. The optical coupler includes a light transmission medium and electrical connectors, which are at least partially encapsulated. In addition, the device includes alignment guides configured to receive guide pins from a fiber optic connector, such that when the fiber optic connector is attached to the optical coupler, fibers of the ribbon align with the two dimensional photonic array device(s) via the light transmission medium.
