- We proposed a high performance eight channel demultiplexer using two-dimensional photonic crystal octagonal ring resonator for wavelength division multiplexing applications. The performance parameters such as transmission efficiency, Q factor, spectral width, resonant wavelength, crosstalk and channel spacing of the proposed demultiplexers are evaluated. The plane wave expansion method manipulates photonic band gap of periodic and non-periodic structure. Finite-difference time-domain method is used to evaluate the performance parameters of designed two-dimensional photonic crystal structure. The proposed demultiplexer provides overall transmission efficiency, Q factor, spectral width of about 98%, 1968 and 0.8 nm, respectively. The ultra-compact eight channel demultiplexer performs better than the reported one. Hence this work can be implemented for real time applications.
