Abstract
Planar optical waveguides have been formed in strontium barium niobate single crystals by either proton or helium-ion implantation. The profiles of the ordinary and the extraordinary refractive indices are deduced from dark-line mode spectroscopy. Optical barriers with depths to Δne = 2.6% for protons and Δne = 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.
