论文摘要
具有较高重复频率的超短脉冲在纳米透明领域具有很高的应用前景。在这里，在连续波发生率的情况下，在由矩形腔，V-Grove（VG）腔和纳米杆组成的传输系统中实现了具有THZ重复频率的飞秒脉冲。半古典dicke模型阐明了具有高重复频率的超短脉冲的发电机理。归因于两级QE的存在，等离子谐振器中的场幅度随时间振荡，导致系统的透射率作为脉冲振荡的形式。此外，脉冲重复频率和灭绝比可以通过入射光强度和QES数密度自由控制，以获得纳米级所需的超短脉冲，该脉冲在光学计算中也具有潜在的应用。
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.
