Abstract

MXenes, a new class of 2D transition metal carbides, nitrides, and carbonitrides, have attracted much attention due to their outstanding properties. Here, we report the broadband spatial self-phase modulation of Ti₂CT_x MXene nanosheets dispersed in deionized water in the visible to near-infrared regime, highlighting the broadband nonlinear optical (NLO) response of Ti₂CT_x MXene. Using ultrafast pulsed laser excitation, the nonlinear refractive index n2 and the third-order nonlinear susceptibility (Formula presented.) of Ti₂CT_x MXene were measured to be ∼10−13 m2/W and ∼ 10−10 esu, respectively. Leveraging the large optical nonlinearity of Ti₂CT_x MXene, an all-optical modulator in the visible regime was fabricated based on the spatial cross-phase modulation effect. This work suggests that 2D MXenes are ideal broadband NLO materials with excellent prospects in NLO applications. (Figure presented.).
