Abstract
In this paper we shows a photonic crystal mach-zender interferometer (MZI) based on new structure by coupled-cavity waveguide using slow light to shorten the length of waveguide arms and nonlinear properties of GaAs for design of an all optical switch. So we comparison with optical switches at arm’s length that approximately is 10m. The design of y-juntion is performed using finite-difference time-domain method. finally the physical principals behind the phenomenon of slow light in photonic crystal waveguide is discussed.
