Query: Ultra-short pulses with high repetition frequency in transmission
  plasmonic systems   Ultra-short pulses with high repetition frequency have great application
prospects in the field of nano-optics. Here, in the case of continuous wave
incidence, the femtosecond pulses with THz repetition frequency are achieved in
the transmission system consisting of a rectangular cavity, a V-groove (VG)
cavity and a nanowire embedded with quantum emitters (QEs). The generation
mechanism of the ultra-short pulses with high repetition frequency is
elucidated by semi-classical Dicke model. Attribute to the presence of the
two-level QEs, the field amplitude in plasmonic resonator is oscillating with
time, resulting in the transmittance of the system behave as the form of pulse
oscillation. Moreover, The pulse repetition frequency and extinction ratio can
be freely controlled by the incident light intensity and QEs number density to
obtain the required ultra-short pulses at nanoscale, which also has potential
applications in optical computing.
