Abstract
Waveguide quasi-phase-matched second-harmonic generation (QPM-SHG) devices are being studied as a promising candidate for realization of a compact short wavelength coherent light source. Efficient LiNbO3 waveguide QPM-SHG devices with ferroelectric-domain-inverted gratings for blue/green light generation have been reported so far [1,2]. Ultraviolet fight generation can give further advantages in many applications such as optical data storage, optical information processing, and optical sensors. In this paper, we present the first fabrication of domain-inverted gratings of ~2 μm period by applying voltage, and demonstrate efficient ultraviolet fight generation in LiNbO3 waveguide SHG device with the grating for 1st-order QPM.
