In this paper, we report on the recent progress in fabrication and high-frequency experiments of Bi 2 Sr 2 CaCu 2 O 8+ x (BSCCO) intrinsic Josephson junctions (IJJs). Using a newly developed double-sided fabrication process, we single out a well-defined number of IJJs in a well-defined geometry from inside a slice of a BSCCO single crystal. We discuss in detail the observations of both Shapiro steps and harmonic mixings in the terahertz region, and we indicate the possible applications in spectroscopy.
