Abstract

Spectral and power properties of inline long Josephson junctions operating in a flux flow regime are investigated using direct computer simulation of the sine-Gordon equation with a noise source. Good agreement of simulation results with the formula for the linewidth [Pankratov, Phys. Rev. B 65, 054504 (2002)] is achieved. The comparison with long Josephson junction of overlap geometry is performed. It is demonstrated that the inline junction has the linewidth which is by a factor of 2 larger than the overlap junction, while the maximal oscillation power is roughly the same in spite of the fact that the velocity-matching step height of the inline junction is much smaller than that of the overlap one.
