▎ 摘  要

Ability of fast intensity discrimination provided by a graphene-based saturable absorber device is demonstrated in the perspective of all-optical signal processing in 1.5 mu m wavelength range. The dynamic extinction ratio enhancement is measured as more than 3 dB. It is argued that, the device performances are promising enough to be tested further in an efficient all-optical module to reduce crosstalk or intensity noise in high rate signals.
