Abstract :
LiNbO3 waveguide first-order quasi-phase-matched second-harmonic generation devices for ultraviolet light generation were fabricated by applying voltage for the first time. Ultraviolet light of 383 nm wavelength was obtained with a domain-inverted grating with 2.0 μm period. A high output of 1.9 mW and a high normalised efficiency of 60%/W were obtained with a 3 mm interaction length
