“…Typically, pillar-based PCs have several advantages such as low out-of-plane losses, propagation loss, easy fabrication, compatibility with classical PICs, and effective single mode operation due to defectsbased structure. 33 Owing to the above mentioned advantages, we conceived a 2-D pillar-type circular PCRR-based ADF design in a square lattice. The details of the circular PCRR-based ADF are discussed in the next section.…”

Abstract. The add drop filter (ADF) is one of the most significant devices for coarse wavelength division multiplexing (CWDM) systems to add and/ or drop a required channel individually from multiplexed output channels without disturbing other channels. The important parameters of the ADF are coupling efficiency, dropping efficiency, passband width and Q factor. Photonic crystal (PC)-based optical devices have attracted great interest due to their compactness, speed of operation, long life period, suitability for photonic integrated circuits, and future optical networks. Here, an extensive overview of a photonic crystal ring resonator (PCRR)-based ADF using a different shape of ring resonator is presented, and its corresponding functional parameters are discussed. Finally, the designed circular PCRR-based ADF for an ITU-T G 694.2 CWDM system is presented. Approximately 100% of coupling efficiency and dropping efficiency, 114.69 of Q factor, and 13 nm of passband width is obtained through simulation, which outperforms the reported one. © The Authors.

“…Also the fabrication of this structure is easier because of simple geometry and can easily control the propagation modes. And, the rod type PCs have several advantages than holes type PCs such as low out-of-plane loss, propagation loss, easy fabrication, compatible with classical photonic integrated circuits, and effective single mode operation [24]. It is witnessed that the pillar type circular Photonic Crystal Ring Resonator (PCRR) offers substantial performance [25] than square, quasi square, dual quasi square and hexagonal PCRRs.…”
