Abstract :
Ultra-violet laser beam writing technique with 2-step voltage application was developed for formation of MgO:LiNbO3 domain-inverted structures. Domain-inverted gratings were fabricated and applied to waveguide quasi-phase-matched second-harmonic generation devices to demonstrate the effectiveness.
