In this paper we used defective resonant cavity for designing a 4-channel photonic crystal demultiplexer. We show that by introducing appropriate waveguides and defects the desired wavelengths can be separated. The platform used for designing the proposed demultiplexer is a square lattice of dielectricrodsimmersedin air. The minimum and maximum transmission efficiency for the proposed structure is 70% and 96% and the channel spacing is less than 1.4 nm. In addition, the maximum value of crosstalk for channels is -10dB. Comparison of the obtained results with other worksdemonstrates that the proposed device has ability to be used in WDM communication applications..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
