Paper Abstract

In 1968, physicist V.G. Beselago pointed out that there always exists negative refractive index in materials when their electric constant and magnetic permeability μ are both negative, and therefore the propagation properties of the EM wave in such materials behave distinctively from those in media with positive refractive index (RI). In this paper, we construct two types of one-dimensional photonic crystals made up with positive and negative RI materials and investigate their nonlinear optical properties. One type of photonic crystals consists of materials with both negative linear and positive third-order nonlinear RIs, the other are mainly made up with a Bragg micro-cavity constructed with both linear positive and negative RIs which contains Kerr media. We show that both types of photonic crystals exhibit bistable switching characteristics. Moreover, as compared with the crystals involved pure positive RI, our photonic crystals possess even lower threshold valve in optical switching.
