Abstract

Optical devices are an undeniable part of the next generation of information technology. One of the main optical devices required in all structures and systems is an optical waveguide, which is responsible for directing light in desired paths within the circuits of the optical complex. This article aims to design and simulate an optical waveguide combining photonic crystals and plasmonic effects. Thus, a new structure is created using silver rods in a type of dielectric substrate to implement an all-optical waveguide based on plasmonic properties based on the Kerr effect. The waveguide's output spectra for different input power values are simulated and the results show that the Transmission component of the designed plasmonic photonic waveguide is over 95%, thus efficiency is suitable enough for communication systems. Also, the range of minimum changes in input power between 1 to 2.25 w/µm² leads to the tuning of desired wavelengths between 1400 to 1440 nm due to the nonlinearity effect of the structure needed for optical data transmission. The cross-section of the proposed structure is 2178 µm² and it is suitable for optical integrated circuits design.
