Quantum wideband traveling-wave analysis of a degenerate parametric amplifier
We develop a wideband traveling-wave formalism for analyzing quantum mechanically a degenerate parametric amplifier. The formalism is based on spatial differential equations-spatial Langevin equations-that propagate temporal Fourier components of the field operators through the nonlinear medium. In addition to the parametric nonlinearity, the Langevin equations include absorption and associated...
متن کاملA near-quantum-limited Josephson traveling-wave parametric amplifier.
Detecting single-photon level signals—carriers of both classical and quantum information—is particularly challenging for low-energy microwave frequency excitations. Here we introduce a superconducting amplifier based on a Josephson junction transmission line. Unlike current standing-wave parametric amplifiers, this traveling wave architecture robustly achieves high gain over a bandwidth of seve...
متن کاملGyro-Traveling Wave Amplifier
The theory, design and experimental results of a wideband 140 GHz, 1 kW pulsed gyro-traveling wave amplifier are presented. The gyro-TWA operates in the HE(0,6) mode of an overmoded quasi-optical waveguide using a gyrating electron beam. The electromagnetic theory, interaction theory, design processes and experimental procedures are described in detail. At 37.7 kV and 2.7 A beam current, the ex...
متن کاملTHEORY OF THE TRAVELLING-WAVE PARAMETRIC AMPLIFIER By Professor
The theory of a parametric travelling-wave amplifier is developed, including the pumping wave explicitly. Particular reference is made to two characteristics of such amplifiers which theories assuming a constant pumping-wave amplitude fail to predict. The first arises from ohmic attenuation in the line, and limits the useful length of line to a length of the order of (ot\a.i)~l, where <xi and 0...
