Depending on structure parameters light can be guided in a single layer or propagate in a matrix of coupled layers in a discrete way. It is also shown that the nonlinear behavior leads to creation of spatial solitons (nematicons) in both discrete and single-layer configurations. <br /> <br />Full Text: <a class="file" href="/PLP/index.php/letters/article/view/1-54/56" target="_parent">PDF</a> <br /> <strong><br />References:</strong> <ol> <li>I.
