NETWORK IMPLEMENTATION OF PHOTONIC CRYSTAL CIRCULAR SPLIT RING RESONATOR BASED ADF

Photonic Crystal based optical devices have attained a widespread attention for ultra-fast communications and Photonic Integrated Circuits. In this paper, Two Dimensional Photonic Crystal Circular Split Ring Resonator (PCCSRR) based Add Drop Filter is proposed and designed. The normalized transmission spectra of circular Photonic Crystal Split Ring Resonator are taken using 2D Finite Difference Time Domain method. The Photonic Band Gap is calculated by Plane Wave Expansion method. The resonant wavelength, coupling/ dropping efficiency and Q factor of the ADF are 1490nm, 100 % and 243nm, respectively. The overall size of the device is much smaller that is 10.4µm × 11.4µm which is highly suitable for photonic integrated circuits and all optical photonic network applications. In addition, the proposed device is incorporated in the point to point networks and its network parameters such as Bit Error Rate, Quality factor, receiver sensitivity are examined.
