For more information of "Perioducally Poled Lithium Niobate", see the section below.
Properties
PPLN has a wide range of useful properties that make it suitable for use in various optoelectronic and photonic applications. It is a birefringent crystal which means that when light passes through it, its polarization state changes depending on the angle at which it was incident. Furthermore, PPLN can be poled with an electric field to create domains where electro-optic coefficients assume different values which allows for a variety of nonlinear effects such as frequency conversion or parametric amplification.
Applications
The potential applications of PPLN are vast and include microwave signal processing, optical switching and routing, visible light communications and waveguide lasers. Due to its capability for nonlinear wavelength conversion and efficient frequency doubling many telecommunications networks now employ components made from PPLN based materials because of their superior performance compared with traditional telecom materials such as silica fiber optics. Other areas where PPLN enables high performance solutions are biotechnology, spectroscopy and quantum optics.
