Abstract

H implantation into bulk and Ti-diffused LiNbO₃ is shown to result in the creation of optically absorbing layers. The induced absorption is characterized, and application to the suppression of optical noise in Ti:LiNbO₃ integrated optical spectrum analyzers is considered. Potential uses include beam dumps, spatial filters, and the absorption of substrate modes.
