Abstract
The nonlinear optical response of four-wave mixing (FWM) in a graphene layer covered on a tapered fiber is numerically investigated. The required graphene length is optimized to realize the maximum conversion efficiency, which is both affected by the incident power and propagation loss. Analysis shows that the graphene length is very short due to the heavy ab- sorption in graphene, and the structure exhibits ultrabroad bandwidth. A conversion bandwidth of more than 300 nm is achieved with a conversion efficiency of more than −30 dB in a wide wavelength range of 0.8–1.8 µm.
