ABSTRACT:
Optical backplanes providing integrated optical couplers to external optical fibers are disclosed, along with methods for making the same. An exemplary optical backplane has a first cladding layer disposed over the top surface of a substrate, and at least a first core body disposed over the first cladding layer, with the first core body having a first end and a second end. A material layer is disposed above the first cladding layer and the first end of the first core body, with the material layer having a top surface and a bottom surface. A focusing element is formed at the top surface of the material layer, with the focusing element being located above the first end of the first core body.
