- Abstract
- We report the observation of the collective transverse plasma(CTP) modes induced by the Josephson vortex lattice motion and the excitation of corresponding electromagnetic waves in a stack of intrinsic Josephson junctions (IJJs) in Bi2Sr2CaCu2O8+x. The existence of the CTP modes was confirmed by observing the sub-branches in the tunneling current-voltage curves of staked junctions in the Josephson vortex-flow region. For a proper bias in the sub-branches, the emission of the electromagnetic waves by the collective vortex resonance motion in a stack of IJJs (the oscillator stack) was examined using another on-chip stack of IJJs (the detector stack). The microwave emission from the oscillator stack and the resulting irradiation onto the detector stack was evidenced by the increase of Josephson vortex-flow voltages in the detector stack.
