Analysis of CWDM network with photonic crystal ring resonator based add drop filter

In this paper, a four channel Coarse Wavelength Division Multiplexing (CWDM) system is designed by incorporating the Two Dimensional (2D) Photonic Crystal Ring Resonator (PCRR) based Add Drop Filter (ADF). The performance parameters of the network such as the received output power, Bit Error Rate (BER) and Q factor are examined for the bit rate of 2.5 Gbps over the fiber length of 50 km and 400 km. The sensitivity of the receiver to get the BER of 10⁻¹² is −19 dBm whose corresponding Q factor is 7. The network design and its simulations are carried out by Optisystem simulator, Optiwave.
