|Title||Nonlinear polarization in metal nanocomposite system based Photonic crystals|
The properties of third-order nonlinear susceptibility in a 1D Photonic crystal (PC) consisting of nanometer sized silver particles embedded in LiNbO3 (metal/dielectric composite materials) are analyzed. By applying temperature with respect to plasma frequency the dielectric permittivity is determined for silver. The temperature increase will undergo a decrease in susceptibility of the material. Due to the variation in temperature, the tuning of a photonic band gap and polariton gap are analyzed thoroughly. These nanostructures are used in ultrafast photonic switches where the optical nonlinearity of third-order susceptibility is combined with light guiding.
