Phys. Rev. Lett. 57, 937–940 (1986)Observation of Berry's Topological Phase by Use of an Optical FiberSee Also: Erratum Received 28 February 1986; published in the issue dated 25 August 1986 We report the first experimental verification of Berry's topological phase. The key element in the experiment was a single-mode, helically wound optical fiber, inside which a photon of a given helicity could be adiabatically transported around a closed path in momentum space. The experiment confirmed at the classical level that the angle of rotation of linearly polarized light in this fiber gives a direct measure of Berry's phase. The topological nature of this effect was also verified, i.e., the rotation was found to be independent of deformations of fiber path if the solid angle of the path in momentum space stayed constant. © 1986 The American Physical Society URL:
