Switching characteristics of forward SIPS in photonic crystal fiber

Forward stimulated light scattering by GHz acoustic resonances (ARs) guided in a μm-sized photonic crystal fiber (PCF) core gives rise to two classes of scattering: forward stimulated Raman-like scattering (SRLS) between pump and Stokes waves in the same optical mode, and forward stimulated inter-polarization scattering (SIPS) between orthogonally polarized pump and Stokes waves. In this paper, the authors study for the first time the transient switching dynamics of forward SIPS, building on previous studies that were restricted to the steady state regime.
