ABSTRACT:
A layered optical circuit including a multi-substrate optical circuit. The multi-substrate optical circuit includes a plurality of optical fibers, a first substrate supporting a first portion the optical fibers to form a first optical subcircuit, and a second substrate supporting a second portion of the optical fibers to form a second optical subcircuit. A third portion of the optical fibers between the first and second portions extends between the first and second substrates. Free fibers in the third portion are elongated to permit repositioning of the first and second optical subcircuits in an overlapping arrangement without exceeding a minimum bend radius of each of the optical fibers. The overlapping arrangement of the first and second optical subcircuits forms a layered optical circuit. Accordingly, a layered optical circuit having a large number of fibers and/or a complex circuit pattern may be affixed on a relatively small footprint of a backplane, etc.
