ABSTRACT:
A technique for interconnecting photonic circuits employing a fixed field of optical couplers situated between adjacent layers of photonic circuits. The coupler field facilitates the direct connection of optical fibers linked to components in one of the adjacent layers of photonic circuits with optical fibers linked to components in another adjacent layer. Each optical coupler within the field is a standard, commercially available optical fiber coupler which mates the optical fibers via a single low-loss connection. In addition, as each of these connectors allows easy connection/disconnection of optical fibers, reconfiguring previous interlayer connections is simplified. In a particular embodiment, the coupler field includes a plurality of individual couplers arranged in a regular geometric pattern upon a panel oriented at a 45.degree. angle with respect to the circuit packs of the adjacent layers. This provides easy access to the couplers, and allows for uncomplicated indexing of each connection.
