Abstract

Index profiles of Ti:LiNbO₃ waveguides can efficiently be reconstructed by measuring the near-field patterns for different waveguide widths. By this, bending losses of curved waveguides can accurately be predicted. The validity of this method is verified by comparing calculated bending losses with those measured for fabricated semicircular waveguides of different bending radii.
