The Optimization of Two-Dimensional Photonic Crystals Resonator (PCR)-based Filter for Telecommunication Applications

The development of photonics technology is growing rapidly due to the promising potential to be applied in various fields, including telecommunications. In telecommunication, data transfer is carried out efficiently at certain wavelengths namely 1310 nm and 1550 nm. In order to obtain the appropriate wavelength and high transmission power, the filter device research is continuously developed. In this study, the silicon photonic crystals resonator (PCR)-based filter has optimized the design. The design parameters such as radius (r) and radius of a defect (rr
1
) were varied with range 0.0715 μm – 0.0745 μm and 0.05 μm – 0. 15 μm, respectively. The simulation with Finite Different Time Domain (FDTD) methods was carried out using Lumerical software. This study resulted in the optimum design of PCR with output wavelength 1550.211 nm with 0.980 of transmission efficiency, with r = 0. 0727 μm and rr
1
= 0.08 μm. Furthermore, the 1284.980 of Q-factor also indicates this design can be produced a narrow band filter. Therefore, the proposed designs of silicon PCR-based filter is prime than other design and potential to produce a high-performance filter for telecommunication applications.
