ABSTRACT

Quasi-phase-matched (QPM) second harmonic generation (SHG) waveguide devices for a green light generation were fabricated by a periodically patterned electrode on the +Z crystal surface and homogeneous LiCl solution using a 5 mol% MgO doped congruent z-cut lithium niobate crystals. Using selective chemical etching, we confirmed the periodic (~6.8 μm) domain inverted structure and measured SHG properties of fabricated periodically poled MgO : LiNbO3 ridge-type waveguides.
