1. A photonic chip, comprising:
at least two programmable photonic analog blocks (PPABs), and
interconnections between the at least two programmable photonic analog blocks (PPABs),
being implemented via a photonic chip,
wherein the at least two programmable photonic analog blocks (PPABs) have the same orientation, and are parallel to each other, and
wherein the interconnections between the at least two programmable photonic analog blocks (PPABs) comprise equally-oriented, programmable, reconfigurable tunable couplers, and
wherein the at least two programmable photonic analog blocks (PPABs) interconnected by the equally-oriented programmable tunable couplers are configured to maintain their orientation while the equally-oriented, programmable, reconfigurable tunable couplers are reconfigured.
