Y. Solomonov et al., COLLINEAR INTERACTION OF ORTHOGONALLY POLARIZED LEAKY MODES IN LINBO3-CU-TI WAVE-GUIDES, Ferroelectrics, 201(1-4), 1997, pp. 195-199
The photorefractive interaction of collinear TE and TM leaky modes in
a structure ''lithium niobate planar waveguide - prism coupling elemen
t'' is experimentally investigated and discussed. At light propagation
along X axis within Y cut waveguide formed in Cu - doped crystal plat
e the photorefractive gratings were produced due to the photogalvanic
current component orthogonal to the grating wave vector and the wavegu
ide plane.
