The profiles of the ordinary and the extraordinary refractive indices are deduced from dark-line mode spectroscopy. Optical barriers with depths to Deltan(e) = 2.6% for protons and Deltan(e) = 5.5% for helium are obtained. By proton implantation we find a very low intensity loss of 0.4 cm(-1) for ordinarily and a higher value of 2.7 cm(-1) for extraordinarily polarized light at 632.8 nm. For helium-implanted waveguides both values are ~4 cm(-1). |
