Abstract
At present, photonic crystals (PhCs) are used to design various combinational and sequential circuits. In this paper, an all-optical one-bit magnitude comparator is proposed using PhC waveguide without using nonlinear material. It is based on beam interference principle, using T-shaped lattice with silicon dielectric rods in air background. It is demonstrated through finite-difference time-domain simulation and verified numerically using MATLAB simulation. The size of PhC lattice structure can be as small as 19.167a×19.167a, where ‘a’ is the lattice constant of the PhC.
