Etching of lithium niobate using standard Ti indiffusion technique
We present evidence of etching LiNbO3 when annealing two wafers in contact with an intermediate Ti strip. Etched features are characterized qualitatively using atomic force microscopy. The impact of the Ti strip thickness on the depth and roughness of the etched surface is quantified. Etched trenches of similar depths to the original Ti film are achieved with very smooth etched surface. © 2007 ...
متن کاملLuminescence and scintillation characterization of Silver doped KCl single crystal grown by Czochralski technique for photonic applications
In this study, the scintillation and optical properties of pure and silver doped potassium chloride (KCl:Ag) single crystals were reported. Pure and doped KCl bulk single crystals with a good optical quality and free from cracks were grown from the melt using Czochralski technique. Different analysis methods were used to study the optical and scintillation properties of the grown crystals. The ...
متن کاملHeterogeneous lithium niobate photonics on silicon substrates.
A platform for the realization of tightly-confined lithium niobate photonic devices and circuits on silicon substrates is reported based on wafer bonding and selective oxidation of refractory metals. The heterogeneous photonic platform is employed to demonstrate high-performance lithium niobate microring optical resonators and Mach-Zehnder optical modulators. A quality factor of ~7.2 × 10⁴ is m...
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...
