Research Abstract

A new simple method for formation of MgO:LiNbO_3 domain inverted gratings was proposed and examined. 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 fairly well with theoretical prediction, and high applicability of the method to QPM device fabrication was demonstrated.
