In the photoisomerized polymerthe perpendicular and all-optical control of optical spatial soliton is simulated by numerical method.The results show that if the controlling beam (c-beam) and the signal beam (s-beam) are coherent, the s-beam under controll of the c-beam will be dispersed, deflected or even collapse. The interactions depend on the difference of the two beam's initial phasesc-beam's intensity and the incident position of c-beam. The effect of perpendicular and all optical control has potential applieations in all-optical switching and optical integration.
