PURPOSE:To process a large amount of informations at high speed by a small- sized device, and to obtain a small-sized signal input/output means by using an optical-fiber for the transmission or reception of the I/O of a computer employing a Josephson junction element and signals with other outsides. CONSTITUTION:A signal processor is constituted by the principal section of an information-processor interface section J.C using a Josephson junction, a high electron moving device G.D mounted on a substrate in GaAs, etc. and a circuit in which a GaAsAl mixed crystal laser-driver LED and a semiconductor photodetector DET are unified. An optical-fiber OP is brought into contact with the LED device side, and each circuit is connected by transfer lines SL1-SL4 and output signals amplified by the device G.D are outputted from the fiber OP as optical signals. In the constitution, each device and the fiber section are immersed in liquid He of 4.2K, and kept at a low temperature.
