“…1,2 At the same time, periodically poled lithium niobate (PPLN), a sort of artificial nonlinear material, received more and more attention owing to its outstanding nonlinear optical properties and its transparent format conversion as all-optical devices in communication band. [3][4][5] As a result of the periodic domain inversion in PPLN, its nonlinear optical coefficient, the electro-optic (EO) coefficient, the acousto-optic coefficient, 6 and the piezoelectric coefficient 7 are modulated periodically. Based on the nonlinear frequency conversion processes in PPLN, some intensity-based all-optical logic gates have been demonstrated already.…”

Based on electro-optic Pockels effect of periodically poled lithium niobate, different polarization-based binary all-optical logic functions: controlled-NOT, XOR, and XNOR gates were demonstrated by altering the linear polarization state of input optical signal about 90° on the polarization plant. Because the depletion of signal intensity in polarization-based logic gates is smaller than that of digital logic signal in intensity-based logic gates and almost negligible, this scheme has potential application in realizing complex logic functions by cascading several basic gates.

“…4 shows also a far more interestingly SH diffraction patterns obtained due to the one-dimensional quadratic square grating, along the x coordinate. The diffraction patterns can be explained by the Raman-Nath [23][24][25][26] and the Cerenkov [27,28] phase matching conditions. In the Raman-Nath case, also known as transverse QPM, the phase matching condition for the m-th diffraction order is defined by the relation…”

Abstract.We develop an approach to fabricate arbitrary ferroelectric domain patterns on lithium niobate film (30-50 μm thick) by applying a structured external field at room temperature. The fabricating method can be operated easily to reach 1 μm linewidth resolution. The ferroelectric domain inversion is stable and uniform. Nonlinear diffraction is generated when the fundamental wave pumps to film. Various nonlinear wavefronts are obtained such as the frequency converted optical vortex beam. A nonlinear holographic concept is proposed to explain the physical phenomena and guide the corresponding domain design. The applications in optical field manipulation and novel photonic states generation are discussed. IntroductionLithium niobate (LN), a typical optoelectronic material, has been widely used in integrated optics due to its excellent nonlinear, electro-optic and acousto-optic properties [1][2][3][4]. Recently, the ferroelectric domain engineering on LN have attracted much attention because of the demand to realize nonlinear wave mixing process, including collinear and noncollinear situations in quasi-phase-matching (QPM) manners [5][6][7][8][9]. While it is difficult to carry out uniform micron linewidth ferroelectric domain inversion on typical 500-μm-thick LN crystal (the coercive field is about 21 kV/mm.) at room temperature as the result of the domain growth from +c facet to -c facet. At the same time, the domain structures will deteriorate soon for submicron LN film (540 nm thick) [10].With the development of domain engineering applications, ferroelectric domain structure with micron or sub-micron linewidth is desired [11][12][13][14]. Here we develop a method to fabricate arbitrary ferroelectric domain patterns on LN film (30-50μm thick) by applying a structured external field at room temperature [15][16]. The ferroelectric domain inversion is stable and uniform with 1 μm linewidth resolution.Based on the pattern poled LN film, it is convenient to observe nonlinear diffraction of vortex beam following the nonlinear holographic principle [8,17]. Furthermore, we can effectively tailor nonlinear wavefronts with designed ferroelectric domain through computer-generation holograms (CGH) [18][19][20]. Also, suitable domain structure could be flexibly introduced into LN for spontaneous parametric downconversion [21].
