We introduced a class of chaotic self-trapped patterns (CSTPs) in nonlocally nonlinear system with sine-oscillatory response, which are induced by the linear chirps. Such chirp-induced CSTPs can exist under a general nonlocality condition, and can be produced by optical beams of any profiles. The CSTPs exhibit both the soliton property and the chaotic property. The mechanism for generating the CSTPs in the nonlinear system with sine-oscillatory response is the multi-reflections by the optical self-induced nonlinear refractive index waveguide, and the multi-interferences between the beams and their reflected counterparts. The interactions of two linearly chirped beams were investigated, which can be controlled by the optical power. We can realize the “ON” and the “OFF” states of light fields by only changing the optical power, and could present a method in the optical switching. •Chaotic self-trapped patterns (CSTPs) are found in nonlocally nonlinear system with sin-oscillatory response.•The CSTPs are induced by the linear chirps and can be produced by any optical beams.•The interactions between two chirped beams can be controlled by the optical power.•The “ON” and “OFF” states of light fields can be realized by only changing the optical power.
