Tailoring entanglement through domain engineering in a lithium niobate waveguide
We propose to integrate the electro-optic (EO) tuning function into on-chip domain engineered lithium niobate (LN) waveguide. Due to the versatility of LN, both the spontaneously parametric down conversion (SPDC) and EO interaction could be realized simultaneously. Photon pairs are generated through SPDC, and the formation of entangled state is modulated by EO processes. An EO tunable polarizat...

متن کاملPhenomenological theory of a single domain wall in uniaxial trigonal ferroelectrics: Lithium niobate and lithium tantalate
A phenomenological treatment of domain walls based on the Ginzburg-Landau-Devonshire theory is developed for uniaxial trigonal ferroelectrics, lithium niobate and lithium tantalate. The contributions to the domainwall energy from polarization and strain as a function of orientation are considered. Analytical expressions are developed that are analyzed numerically to determine the minimum polari...
متن کاملCalligraphic poling of Lithium Niobate.
We demonstrate a novel technique for instituting complex and arbitrary shaped micron-scale domain patterns in LiNbO3 at room temperature. Fabrication of continuous domains as narrow as 2 microm across and hexagonal patterns of the same order accompanied by real time visualization of the poling process are presented.
متن کاملGbit / s Lithium Niobate Modulator
As 10 Gbit/s long-distance optical communication systems become more and more pervasive, requirements rise relating to increased levels of performance, as well as the miniaturization of key devices that configure such systems. Lithium niobate (LN) modulators are used primarily as optical modulators that change high-speed electrical signals at 10 Gbit/s to optical signals for long-distance commu...
