In this paper, using surface plasmon resonance effect, we demonstrate an optical OR gate. We have used gold and silver because of low losses of silver and gold in visible regime compared to other metals. The photonic crystal structure consists of a hexagonal lattice of iron nano rods, with a radius of r=50 nm and lattice constant of ɑ=200 nm, in a background of air. The designed optical gate, works in the wavelength of λ=0.65 μm with the TM (Hz,Ex,Ey) polarization. Simulation of this structure is done using the COMSOL software package.
Keywords: surface plasmon, Photonic crystal, optical gate.
