We put forward a new method to realize optical label switches using the phase shifted effective in Bragg phase shifted grating and device a experiment to achieve optical label switching. The grating is written in a standard fiber for communication and optical label switching is based on the cross phase modulation induced by an intense pump pulse on a low intensity probe
