Few-layer TaSe 2 nanosheets are prepared by liquid-phase exfoliation, the nonlinear optical response of which is researched based on the spatial self-phase modulation effect. The large nonlinear refractive index and the third-order nonlinear susceptibility have been confirmed experimentally. Based on the cross-phase modulation technique, the attractive nonlinear optical responses of 2D TaSe 2 nanosheets have been utilized to realize all-optical switching. It is shown that a strong controlling light beam can change the phase of weak signal light, leading to the novel all-optical switching phenomenon. Based on the all-optical switching, we propose information transfer by using a baffle to control the mode of input signal to achieve the synchronized control of the output signal. Our experimental results have great potential applications in all-optical information transmission, all-optical switching, photoelectric detectors, and laser devices.
