All-optical NOT logic gate in the basis of the oblique photonic waveguide structure has been proposed in this paper. The structure of Photonic crystal lattice is triangular and it is formed of dielectric rods in air substrate. The simulation is done using oblique and crossover waveguide structures and a scatter rod in this design. The location of the scatter rod has been selected such a way that the logic gate act as a NOT function in both directions of the structure. The simulated required power consumption becomes200mw for operation of the logic gate. Waveguide bend was used to increase transmission optical power in the proposed scheme and the nonlinear rods were not used which lead to a reduction in the power consumption of the logic gate. Switching time is simulated 0.51ps and extinction ratio of this logic gate becomes9.6 dB. Calculation methods were based on the FDTD and PWE methods.
