Design and Analysis of all Optical Multiplexers using 2D Photonic Crystal

Abstract

The development of an all-optical, two-dimensional photonic crystal waveguide multiplexer (MUX) for optical signal processing and networking is the focus of this study. The paper proposes the design of 4×1 all optical multiplexer based on 2-D photonic crystal. The architecture, which has an air-filled background, uses two silicon square lattice rod T-shaped waveguides and one silicon square lattice rod Y-shaped waveguide. All-optical MUX developed the use of nonlinear materials, such as Kerr, to address challenges of less profit and nonlinearity. The beam-interference phenomena serve as the inspiration for this design. The performance of the optical MUX is modelled using a finite-difference time-domain method, and the results are then verified to employ the 1.55 m wavelength optical field distribution.
