Graphene has become a promising nonlinear optical medium due to its ultra-high nonlinear coefficients and tight light mode confinement ability. By optimizing the geometry parameters, a 3.9-mm-long graphene-covered silicon ridge waveguide is demonstrated, resulting in a maximum bandwidth of 498 nm and a peak conversion efficiency of -15.2 dB in mid-infrared band, with the pump power of 1 W. The results in this article show that graphene has unparalleled potential in the field of nonlinear optics.
