Abstract
Planar waveguides are built up (around 300 K) in lithium iodate by means of proton implantation. The waveguide properties are investigated by a prism coupling technique (m-lines spectroscopy). Both TE and TM modes are used to investigate the ordinary and extraordinary indices. The reconstructed index profiles obtained with inverse WKB method, are compared to the ion concentration profile as determined by simulation (TRIM). All the measured effective index values are smaller than these of the bulk indices. Moreover, the optical barrier is relevant to a maximum index change of about 0.03.
