We report what is believed to the first example of graded index multimode fiber slanted grating. The gratings are realized by the same technique as the single mode fiber gratings. The periodic perturbation causes fundamental core mode to higher order core modes, cladding modes and radiation modes coupling. There is a unique feature in the spectra of certain angle-slanted gratings (2.5°-4°). Hope this phenomenon can cause a new type of fiber components that can be widely used in the LAN and sensing systems.
