Josephson generation is good for pixel in the array of passive imaging system

One of the critical technologies is combining both of superconductive and semiconductor technologies on a single substrate, including creating Josephson junction (JJ) near the gate of a semiconductor transistor. The use of JJ in self-pumping mode regime as one of the heterodyne detection methods can provide a new trend for designing modern passive terahertz imaging system. Further development will allow to realize multi-spectrum systems with electronically tunable band. This paper discussed the theoretical analysis on the noise characteristics of the JJ as the pixels in the array of passive imaging system. The analytical result shows that JJ is a possible solution to improve the sensitivity of modern multi-spectrum passive imaging systems.
