The role of ion and electron kinetic effects in the nonlinear evolution of stimulated Brillouin scattering (SBS) is investigated by means of particle-in-cell numerical simulations. The simulations were carried out in one and two spatial dimensions (1D and 2D), with a full PIC code, in which both ions and electrons are kinetic. The full PIC simulations are compared with those obtained from a hyb...
We experimentally demonstrate a novel tunable true-time delay line with separate carrier tuning using dual-parallel Mach-Zehnder modulator and stimulated Brillouin scattering-induced slow light. The phase of the optical carrier can be continuously and precisely controlled by simply adjusting the dc bias of the dual-parallel Mach-Zehnder modulator. In addition, both the slow light and single-sid...
Stimulated Brillouin scattering with both pump and Stokes beams in resonance with whispering gallery modes of an ultrahigh Q calcium fluoride resonator is demonstrated for the first time. The resonator is pumped with 1064 nm light and has 3 muW Brillouin lasing threshold. The scattering is observed due to the unique morphology of the resonator reducing the phase mismatch between the optical mod...
Stimulated Brillouin scattering (SBS) is the major factor that limits maximum optical fiber output power in narrow linewidth applications, which include important fields such as passive networks (PONs), high-power amplifiers, and lasers. Great efforts have been dedicated to suppressing SBS effect increasing power. This paper focuses on key fiber-based techniques suppress SBS. These take advanta...
Stimulated Brillouin scattering (SBS) has many applications, for example, in sensing, microwave photonics and signal processing. Here we report the first experimental study of SBS chiral photonic crystal fiber (PCF), which displays optical activity robustly maintains circular polarization states against external perturbations. As a result, circularly polarized pump light is cleanly back-scatter...
