| Abstract(in English) | In order to examine the intrinsic noise temperatures(T_N) and the operation frequency limit, the response of YBCO Josephson junctions to milimeter wave and far infrared(FIR) laser radiation in the operation temperature(Tp) range from 4.2K to 77K, has been studied. It was found that T_N can be minimized to Tp even in such wide range of operation temperature. Also, T_N were not affected by external magnetic field no by microwave radiation working as an LO signal for harmonic mixers. As to the operation frequency, it was denonstrated that Josephson junctions could operate well into the THz range. |
