Homodyne detector, heterodyne detector and generator device for electromagnetic radiation

摘要

The detector and generator carries out its functions in the high temperature superconductive layers of the device. These layers are grown epitaxially on a substrate, so that the C-axis of the superconductor is tilted with respect to the substrate surface normal. The high temperature superconductive layer can be in a superconductive mode, or in a transition from normally conductive to the superconductive mode. A current is actively introduced into the high temperature superconductive layer, and the heterodyne detection local oscillator is of an external type, or may be an internal generator.
