Abstract:The propagation losses (PL) of lithium niobate optical planar waveguides fabricated by swift heavy-ion irradiation (SHI), an alternative to conventional ion implantation, have been investigated and optimized. For waveguide fabrication, congruently melting LiNbO 3 substrates were irradiated with F ions at 20 MeV or 30 MeV and fluences in the range 10 13- 10 14 cm -2. The influence of the temperature and time of post-irradiation annealing treatments has been systematically studied. Optimum propagation losses lower than 0.5 dB/cm have been obtained for both TE and TM modes, after a two-stage annealing treatment at 350 and 375°C. Possible loss mechanisms are discussed. © 2012 Springer-Verlag.
