  • Abstract
    A new simple method for formation of MgO:LiNbO3 domain inverted gratings is demonstrated. Periodic domain structure was formed on -z face by first voltage application under ultraviolet (UV) light with periodic intensity distribution. Following second voltage application without UV resulted in periodic structure continuing through crystal thickness. A waveguide quasi-phase-matched (QPM) nonlinear-optic device was fabricated by the method and characterized. The device performance agreed with approximate theoretical prediction, and high applicability of the method to QPM device fabrication was demonstrated.
