Anisotropic Terahertz Pump-Probe Response of Bilayer Graphene

Bilayer graphene features many of the interesting properties of graphene such as high carrier mobility and nonlinear optical properties over a wide range of frequencies, from THz to visible. Here we investigate the nonlinear, anisotropic response of doped bilayer graphene to pulsed, linearly polarized, in-plane THz fields.
