1 Growth and Properties of Ru Doped Lithium Niobate Crystal
Ruthenium (Ru) doped lithium niobate (LiNbO3) single crystal was grown by the Czochralski method from a congruent melt composition. The color of the Ru: LiNbO3 was red and darkened with the increasing Ru concentration. The amount of Ru concentrated in the grown crystal gradually decreased along the pulling direction because the effective segregation coefficient of Ru in lithium niobate is great...
متن کاملDesign of nano-groove photonic crystal cavities in lithium niobate.
We propose a novel design of photonic-crystal nanobeam cavities in lithium niobate (LN) for both TE and TM modes, addressing problems associated with tilted sidewalls, which commonly result from dry etching. Using optimized periodical nano-groove structures, the proposed devices could achieve quality factors as high as 3.9×10(6) with a modal volume of 5.0 (λ/n)3. We also show that such a design...
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 کاملKey words: Fractionation of hydrogen isotopes, Aqueous lithium chloride solution. Hydrophobic platinum catalyst, Dependence of D/H fractionation on molality, Comparison of hydrogen and oxygen isotope effects. Introduction
The D/H ratio of hydrogen gas in equilibrium with water vapor over aqueous lithium chloride solutions was measured at 25 °C, using a hydrophobic platinum catalyst. Experimental details are described. The hydrogen isotope effect between the solution and pure water depends linearly on the LiCl concentration up to ca. 12 m, and at higher concentrations a marked deviation from linearity takes place...
متن کاملSuspended slab and photonic crystal waveguides in lithium niobate
Suspended waveguides have been widely applied to silicon-on-insulator structures because they are easily fabricated with processing techniques similar to those of integrated circuit design. However, it is difficult to fabricate such structures in lithium niobate, which is also a very important material for optoelectronics. One main challenge is the difficulty of etching lithium niobate. In this...
