Stacked Ferrules for On-Board Optical Interconnects

(canceled)

A plurality of optical ferrules, each of the optical ferrules comprising a light redirecting member configured to receive, along a first direction, one or more central light rays emitted from a corresponding one or more optical waveguides attached to the optical ferrule and redirect the one or more received central light rays along a different second direction as one or more redirected central light rays, the redirected central light rays exiting the optical ferrule through an exit window of the optical ferrule as one or more exiting central light rays, each of the one or more exiting central light rays of each of the optical ferrules passing through a different exit location of the exit window of a same optical ferrule in the plurality of the optical ferrules.

An optical stack comprising a plurality of optical ferrules assembled along thickness directions of the optical ferrules, each of the optical ferrules configured so that a plurality of central light rays emitted by a corresponding plurality of optical waveguides optically coupled to the optical ferrule enters the optical ferrule along a first direction and are bent by the optical ferrule so as to exit the optical stack through a same exit surface of the optical stack along a different second direction, wherein the central light rays entering each of optical ferrules along the first direction exit the optical stack through the exit surface of the optical stack after going through every of the other optical ferrules that may be disposed between the optical ferrule and the exit surface.
