Quantum wires in lithium niobate : first realizations and characterizations

Description

The proton exchange technique allows fabricating a great variety of waveguides in Lithium Niobate. Recently we discovered that it was possible to realize highly confining waveguides in a controllable manner and without destroying the nonlinear and electro-optic properties of the crystal. With this technique, one can fabricate quantum wires in both X-cut and Z-cut wafers, and the properties of those will be presented as well as the possibility to combine this technique with periodic poling and photonic crystal fabrication.
