Abstract

PURPOSE:To obtain the tunnel type Josephson element which will have a voltage-existing condition and a zero-voltage condition in accordance with the irradiation and non-irradiation of the beam of light by a method wherein a light- transmitting property is given to a super conductive electrode. CONSTITUTION:In the tunnel type Josephson element having a super conductive electrode 2 provided on a Vycor glass substrate 1 and a super conductive electrode 4 provided oposing the electrode 2 through the intermediary of a barrier layer 3, the property of light transmission is given to these super conductive electrodes 2 and 4. This can be accomplished by having the super conductive electrodes 2 and 4 composed of a light-transmitting material such as BaPb1-xBixO2 (in the form of 0.05<x<0.3), for example, or the electrodes 2 and 4 are formed thinly (0.05mum, for example) so that the light can be transmitted. Subsequently, a laser beam is irradiated through the substrate 1 and the super conductive electrode 2, or through the super conductive electrode 4. Accordingly, the state between the two super conductive electrodes can be changed from a zero-voltage condition to a voltage-existing condition by the irradiation of the laser beam, thereby enabling to obtain a light-controlled type switching element.
