Efficient 1×2, 1×4, 1×8 and 1×16 photonic crystal filters/power splitters based ring resonators for modern passive optical network PON.

In this paper, we propose a new architecture of 1 × 2 , 1 × 4 , 1 × 8 and 1 × 1 6 optical filter/power splitters operating around 1.55 μ m, based on a CPs 2D photonic crystal ring resonator for Modern Passive Optical Network (PON). This type of functionality, filtering/power splitting is introduced in this work for the first-time according literature. The designed device consists of a square array of GaAs dielectric rods immersed in air. The structure is designed and successfully simulated by the finite element method using the software COMSOL Multiphysics. From the results obtained, we note that the beam is evenly distributed for all output ports with total efficient transmissions of about 99.6%, 98.8%, 97.1% and 96.8% and low insertion losses of about 0.017, 0.052, 0.128, and −0.14 dB for the 1 × 2 , 1 × 4 , 1 × 8 , and 1 × 1 6 filter power splitter successively.
