Simulations of Dipole-Dipole Interaction in Nonlinear Photonic Crystals Doped With Nanoparticles

摘要

We have performed numerical simulations on the dipole-dipole interaction in a nonlinear photonic crystal doped with nanoparticles. A pump field is applied to change the refractive index of the crystal. It is found that as the intensity of the pump field increases the crystal goes from absorption state to the transparent state and remains in the later state. The present mechanism can be used to makes optical switches, optical memory, optical transistor, optical discriminator, optical limiter, optical oscillator, optical gate etc.
