Abstract

In this paper, All-optical AND logic gate with square cavity in 2-D (two dimensions) photonic crystal with GaAs have been demonstrated. The square cavity is created by removing rods from a rectangular lattice of dielectric cylinders in air substrate. Photonic crystal (PC) has periodic dielectric structure that has an important characteristic of PC and that is known as photonic band gap (PBG). The property of PBG is that, wavelength within the band gap cannot propagate through the crystal. In this research work, this property is used to design an All-optical AND logic gate. The operation of this logic gate is verified at third optical window i.e. 1550 nm, which is the most widely used window in present optical communication system.
