Fig. 2. Numerical propagation of focused STOV pulse in few-mode fiber. (a) Unchirped focused STOV pulse; (b) unchirped focused STOV pulse with GVM between LP modes set at zero; (c) unchirped focused STOV pulse with GVD of each LP mode set at zero; (d) chirped focused STOV pulse.
Fig. 3. Schematic for transmitting and measuring STOV pulse through few-mode optical fiber. The system is pumped by a home-built Yb:fiber laser system. One replica of the laser output is spatiotemporally modulated to a STOV pulse. It is then coupled into a few-mode fiber (SMF-28) by a high-NA aspherical lens mounted on a 3D translation stage. Another replica of the laser output is compressed and delay-controlled to serve as a probe pulse to measure the transmitted STOV pulse.
