Abstract
The impacts of strain along the zigzag and armchair directions on optical properties of graphene have been investigated theoretically by first principles. The relative changes of the refractive index achieve up to 1 with increasing polarized angle at some frequency points for both cases. It must be noted that strain along the armchair direction results in an additional infrared absorption peak at 1511[Formula: see text]cm[Formula: see text], because the electron concentration is inhomogeneous at the direction of atomic vibration. Thus, this work paves the way of strained graphene application in identifying polarization of light and infrared sensors in near future.
