    "abstract": "The evolution of the transverse momentum of monochromatic light entering a\nmultimode planar waveguide at large angle is investigated. We report on\noscillations of the momentum caused by the beatings between the adjacent\npopulated modes of the waveguide and their periodic collapses and revivals. A\nnew type of an interferometer based on this effect with fringe spacing as small\nas 1/9 of a light wavelength is demonstrated experimentally and periods as\nsmall as 1/1000 of a light wavelength seem to be feasible.",
