| Zusammenfassung | We have developed a recently proposed concept of a Josephson traveling-wave parametric amplifier with threewave mixing. The amplifier consists of a microwave transmission line formed by a serial array of nonhysteretic one-junction SQUIDs. These SQUIDs are flux-biased in a way that the phase drops across the Josephson junctions are equal to 90 °. Such a one-dimensional metamaterial possesses a large quadratic nonlinearity and a minimal cubic (Kerr-like) nonlinearity. This property allows phase matching and exponential power gain to take place over a wide frequency range. The proof-of-principle measurements performed at a temperature of T = 4.2 K on Nb trilayer samples have demonstrated that our concept of a practical broadband Josephson parametric amplifier is valid and very promising for quantum-limited performance. |
