  In this paper, we consider the focusing fractional nonlinear Schr\"{o}dinger
equation (FNLS) on the waveguide manifolds $\mathbb{R}^d\times\mathbb{T}^m$
both in the isotropic and anisotropic case. Under different conditions, we
establish the existence and periodic dependence of the ground states of the
focusing FNLS. In the intercritical regime, we also establish the large data
scattering for the anisotropic focusing FNLS by appealing to the framework of
semivirial vanishing geometry.
