Abstract
A proposal for implementation of optical logic gates using a two dimensional closed packed photonic crystal structure is presented here. The logic operations are realized by a control signal and the input signal(s) applied across two adjacent faces, while the output is obtained along one of the remaining faces. Finite Difference Time Domain simulations show that, this structure can be used to realize AND, OR, NOT, XNOR, NAND operations, if phase difference of Ï/2 is maintained between the control and the input signal. Further it is found that the same structure can be used as a switch, if Kerr nonlinearity is introduced to the dielectric rods constituting the photonic crystal structure.
