We demonstrate a nonvolatile multilevel optical switch used by GST integrated on a graded-index multimode fiber. This optical switch works by the crystalline state and the amorphous state of the GST. The present experimental results demonstrate the feasibility of 11 multilevel states in the field of optical fibers commonly used in communications.
