Abstract: This paper deals with designing and simulation of all optical NOT gate constructed by using 2-D modified Photonic Crystal. A typical NOT Gate can be constructed on square lattice of 8 µm*8 µm photonic crystal of silicon rods in doped substrate with refractive index of 3.40 and 1.1 respectively. The lattice constant ?= 1µm and radius of the rods r= 0.2?µm. Not gate is realized by combining the cross-waveguide geometries and varying its diameter by pitch (d/?). The gate is implemented for the operating wavelength of 1.55µm using Rsoft's Fullwave simulator.
