A controllable optical anisotropy in CVD graphene is shown. The transparency in the visible range of pre-strained CVD graphene exhibits a periodic modulation as a function of polarization direction. The strain sensitivity of the optical response of graphene demonstrated here can be effectively utilized towards novel ultra-thin optical devices and strain sensing applications.
