Paper Abstract

The optical damage resistance of diffused lithium niobate waveguides is reviewed. Long-term laser-power-handling performance is assessed by recording the spatial intensity changes occurring as a function of time in a waveguide's far-field. Out-diffused waveguides are found to offer significantly greater long-term resistance to optical power-losses caused by optical damage than do wavegudies formed by either ion-exchange or titanium-in-diffusion. Any waveguide's resistance to optical damage is lowered by inadvertant exposure to chemical reducing conditions that can prevail during device fabrication processes. Waveguides exposed to the severe chemical reducing conditions are found to exhibit dramatically non-linear behavior when exposed to high laser powers and short laser wavelengths.
