Optical signal processing based on 2D materials is a hot topic which has attracted rising interests. As a novel class of 2D material, MXene is becoming a promising nonlinear photonics material. In this contribution, MXene Ti 3 C 2 T x , prepared by liquid acid etching method, is developed as a novel all‐optical device by depositing on a microfiber, which shows an excellent nonlinear optical response at the telecommunication band. The as‐fabricated device is employed as a wavelength converter based on the nonlinear four‐wave mixing effect with a conversion efficiency of –59 dB carrying a 10 GHz signal. The proposed all‐optical wavelength converter based on MXene Ti 3 C 2 T x can play a remarkable role in the future of optical communications and optical information processing.
