A method of optical waveguiding, based on Bragg diffractions from a 1D grating was presented. The method was shown to gives rise to waveguiding in the direction normal to the grating wave vector. The structure consisted of a shallow 1D grating that had a bell or trough shaped amplitude in the confinement direction. An experimental proof of the concept for the mechanism was also presented.
