We are going to design an optical Majority gate.Photonic crystals will be used for designing thisstructure. Resonant cavities are used to realize thethreshold switching for the working mechanism of theoptical Majority gate. Doped glass rods are added tocavities to create the nonlinear cavities. The simulationsare done with Rsoft photonics CAD based on finitedifference time domain method. The proposed majoritygate has 3 input ports and only one output port. Theoutput port is ON, when at least two of the input portsare ON. The working wavelength of the proposedstructure is 1550 nm. For the proposed all opticalmajority gate the ON/OFF contras ratio and the bit rateare 19.5 dB and 500 GS/s respectively.
