Abstract

The use of the intrinsic Josephson effect in layered high-Tc superconductors for amplification of a signal in the presence of a strong pump radiation is investigated. Calculations are done both for thin films and massive material with a surface parallel to the c-direction, assuming normal incidence of the radiation with electric field parallel to the c-direction for parameter values relevant for high-Tc materials. In both cases high signal gain is obtained in a limited range of frequencies and pump power.
