Abstract
The optical-electrical printed circuit board disclosed herein includes a waveguide link assembly and a printed circuit board assembly. The printed circuit board assembly has first and second PCB layers between which optical waveguides of the waveguide link assembly are disposed. The end faces the optical waveguides are accessible through an access aperture in the printed circuit board assembly. An optical interconnector can be used to optically connect the optical waveguides to waveguides of an optical-electrical integrated circuit operably disposed on the printed circuit board assembly to form a photonic device. A waveguide bending structure can be used to bend the optical waveguides to facilitate optical coupling to the optical interconnector or directly to the waveguides of the optical-electrical integrated circuit. Methods of forming an optical-electrical printed circuit board, a photonic assembly and a photonic device are also disclosed.
