Very broad band throughputs greater than 1T bit/sec are desired in heavily loaded communication systems. Using the merits of superconducting devices, a superconducting network system is expected to improve the throughputs of such communication bottleneck systems. The paper describes a superconducting packet switch which is indispensable to a proposed superconducting network system. Considering the characteristics of various switch architectures, the space-division Banyan type architecture is adopted for a superconducting packet switch proto-type. The complete design of the proto-type is performed and the total operation is numerically simulated and confirmed. A 2/spl times/2 switching element which controls the paths of two packets is a key component of the proto-type. The basic switching element with one-bit data width is fabricated and the correct operation is completely confirmed.>
