| Abstract | Introduction: Lithium Tantalate (LT) has a shorter cut-off wavelength than Lithium Niobate (LN) which makes the material attractive for UV generation through nonlinear processes. While congruent LT (CLT) suffers strongly from photorefractive damage, MgOdoped LT (MgO:LT) is an interesting alternative as it was shown on LN that MgO reduces the photorefractive effects. On the other hand, fabricating highly confining, low-loss optical waveguides on LT while preserving its nonlinear properties is still an issue, as it was previously shown that the index variation obtained using proton exchange is one order of magnitude lower than that on LN and that direct Proton Exchange (PE) erases both nonlinear coefficient and periodic domains organization as on LN. |
