We experimentally demonstrated adaptive control of linearly polarized (LP) modes in a two-mode fiber. Our method is based on a stepwise adaptive optics algorithm, with feedback determined by the relative magnitude of optical power reflected by a fiber Bragg grating and the transmitted power. Selective excitations of the LP01 and LP11 modes are experimentally shown.
