Abstract

In nonlinear optics applications employing quasi- phasematching, short pitch domain gratings are generally required for the generation of visible and ultraviolet light. The conventional electric-field poling method enables the fabrication of periodically-poled lithium niobate (PPLN) down to generally 6 micron-pitch domains in 0.5-mm-thick substrates. While such PPLN is useful for first-order second harmonic generation (SHG) of green wavelengths, shorter periods for blue and UV SHG have been difficult to obtain in 0.5-mm-thick substrates. Here we describe an enhanced electric-field poling technique for ferroelectric materials which utilizes spontaneous flip-back towards high-resolution and high-yield domain patterning.
