Introduction
Metamaterials with unavailable optical properties in nature such as the negative refraction, have been studied extensively from opticalto microwave frequency ranges [1]. They show a wide range of new applications such as sub wavelength image [2], slow light and cloaking [3]. In many cases, metallic resonators such as split ring resonators (SRRs) and fishnet structures are used to demonstrate the negative index metamaterial [4,5]. The design of all optical switches based on SRRs has attracted a great deal of attention in recent years, however only a limited number of materials have been used in their design and fabrication. For example, Chen et al. [6] have proposed a structure for terahertz electro optical switch based on SRRs and Gong et al. [7] have investigated theoretically an all optical absorption switch using an effective medium which its strong Kerr nonlinear effect has been discussed in [8].
