ABSTRACT

Photonic crystals are used in the design and manufacture of optical devices. One of these applications is photonic crystal filters. The advantages of the design of photonic crystals-based multi-channel filters are small size, flexibility in changing the parameters, low loss, and ability to separate wavelengths in the nanometer range. This paper proposed a two-channel filter using photonic crystals with a square lattice. This simple structure has small dimensions and causes separation of the wavelengths very close together, using defect routes. A waveguide has been created by eliminating all the rods to transfer waves from the input to the outputs. In addition to separate wavelengths, two other defect routes have been created, containing line and point defects. The results show that the wavelengths at a distance of a few nanometers of each other can be separated.
