Ultrafast spatiotemporal control of the femtosecond Bessel surface plasmon polariton by a chirped laser pulse

Nondiffracting Bessel surface plasmon polariton (SPP) beams, which have unique self-healing, non-divergence, and linear transmission properties, have charming applications in plasmonic devices and on-chip interconnection circuits. Here we first realize, to the best of our knowledge, the ultrafast control and imaging of the Bessel SPP pulse on the nano-femto scale in the experiment. We demonstrate ultrafast control of Bessel SPP pulse switching by controlling the instantaneous polarization state of the excitation light. Moreover, this variation process is directly mapped on the nano-femto scale by time-resolved two-color photoemission electron microscopy. The results are well reproduced by the finite-difference time-domain (FDTD) method. The current study of ultrafast control and spatiotemporally imaging the switching process establishes an experimental paradigm for revealing the complex mechanisms in ultrafast control of nondiffracting SPP and are useful for developing high-speed, highly-integrated nanophotonic devices, and on-chip circuits.

In the recent decade, single-shot ultrafast optical imaging by active detection, called single-shot active ultrafast optical imaging (SS-AUOI) here, has made great progress, e.g., with a temporal resolution of 50 fs and a frame rate beyond 10 trillion frames per second. Now, it has become indispensable for charactering the nonrepeatable and difficult-to-reproduce events and revealing the underlying physical, chemical, and biological mechanisms. On the basis of this delightful status, we would like to make a review of SS-AUOI. On the basis of a brief introduction of SS-AUOI, our review starts with discussing its characteristics and then focuses on the survey and prospect of SS-AUOI technology.
