Abstract :
Periodic electric field assisted poling of low-loss (~0.1 dB/cm) singlemode Ti-diffused channel waveguides in MgO (5 mol%):LiNbO3 has been achieved for the first time using a periodically patterned metal electrode under vacuum conditions and a homogeneous liquid ground electrode at atmospheric pressure. Using selective chemical etching, the periodic (Λ~17 μm) domain inverted structure is confirmed
