Graphene microfibers are burgeoning modulators with great potential in all-optical communication. One of the critical issues that remains to be understood is dynamic mechanism light–graphene interaction. Here, we propose a power dependent modulation by using 980 nm pump light and 1064 nm signal via graphene microfiber, results show strong transmission reduction frequency blue shift increase power. The experimental observation attributed stimulated Brillouin scattering process induced light. Power variations result energy transition scattered phonon fiber. This work reveals nonlinear effect interaction provides new method for control modulation.
