The article analyzes a nine-channel Wavelength Division Demultiplexer based on a two-dimensional photonic crystal lattice. In the design of the device, defects and air holes are shifted in the resonant cavities: by changing characteristics such as radii of defects, distance between them and position of defects, a compact optical filter circuit is designed with a 1 nm channel spacing. The properties of these devices are investigated using finite-difference time-domain method. The resonant wavelengths of nine channel demultiplexers are 1481.4, 1503.7, 1526.6, 1538.4 ,1550.3, 1562.3, 1574.7, 1587.2 and 1612.9 nm. The value of transmission efficiency for channels was obtained in 79-96% range. In addition, the maximum value of crosstalk and average quality factor for channels were calculated -11.3 dB and 2000, respectively. The overall size of the structure is small (11.3 μm × 15.3 μm) which is suitable for photonic integrated circuits and optical communication network applications.
