Photonic - Crystal Splitters based on Waveguide

A photonic crystal waveguide is provided in this article. The structure is two-dimensional array of silicon bars arranged in a triangular arrangement. Rods is placed in the air background and the x-z surface.  The waveguide structure is created by removing the silicon bars. In this splitter, band gap arrangement was investigated by FDTD method. The waveguide can play the role of a splitter. With this array, a two-port and three-port splitter has been created. The two-dimensional Splitter leads the waves in two channels. The three-port splitter permits electromagnetic waves to be emitted with a 180 ° phase shifted between output signals. In this three-port splitter, the measured transmission spectra shown that the guided mode can be separated into three different lights. Since the splitter is made up of the photonic crystal structure, it has fewer losses. This issue is an important matter in the photonic circuitry.
