Polarization-dependent methanol adsorption on lithium niobate Z-cut surfaces

The adsorption of single methanol molecules on the lithium niobate (0001) surface, commonly referred to as Z-cut, is investigated using first-principles calculations. It is found that the binding energy for molecular adsorption on the negative surface (∼1 eV) is about twice as large as for the positive surface. This difference is related to different bond strengths rather than electrostatics. D...

Programmable Coupler Ladder Based on Lithium Niobate Y-Junction Reflector

This paper presents a proposal for a novel integrated tun-able coupler device called programmable coupler ladder, based on Titanium diffused lithium niobate waveguide and Y-junction reflector. Unlike the traditional serial to parallel converter, the coupler ladder sorts the output bits in the time axis using a built-in delay waveguide. With a proper control signal it can perform signal processi...

Dielectric properties of lithium niobate single crystals doped with gadolinium

In this paper dielectric properties of LiNbO3:Gd single crystals at temperatures ~ 290–490 K at narrow frequency range (0.5–10 6 Hz) are presented. The influence of growth conditions was also investigated. The anomalies on dielectric plots depend on the development of the microand nano-domain structure.

Calligraphic 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.
