Abstract
An ultra high speed and high sensitivity photo detecting element is fabricated by laminating thin film layers of superconducting material and ferromagnetic material on a substrate. A photo detecting element composed of a photo detecting portion formed on a substrate by laminating alternately at least a thin film layer of ferromagnetic material and at least a thin film layer of high temperature superconducting material between which a thin film layer of insulating material is sandwiched and electrodes connected to the photo detecting portion.
