Abstract
Superconductized electronic devices, such as a Josephson junction device, or superconductized optical devices represented by a light emitting and receiving devices of semiconductor laser are available using semiconductor materials which normally have no superconducting characteristics. The devices can operate by controlling the behavior of a Cooper pair in an active region which is formed in the semiconductor in advance using the penetrating phenomenon of the Cooper pair caused in the semiconductor proximate to the superconductor.
