Abstract

Contradirectional two-beam coupling was achieved using a single laser beam incident on fibers grown from congruent iron doped lithium niobate using the laser heated pedestal growth technique. To our knowledge, this is the first time that a grating has been written in a fiber using a single laser beam and its Fresnel reflection in a 180 degree(s) contradirectional two-beam coupling geometry. Beam-coupling efficiencies were compared as a function of beam spot size for fibers and bulk crystals. At small spot sizes, the fibers outperformed the bulk crystals by reducing the diffraction effect.
