摘要：
This study has proposed a 6-channel wavelength division demultiplexer based on photonic crystal ring resonators suitable for Wavelength Division Multiplexing (WDM) applications. For this purpose, a demultiplexer of six resonance rings with geometrical parameters has been used with a square grid of two-dimensional photonic crystal structure consisting of dielectric rods as the basic structure for designing a demultiplexer that has two photonic band gap (PBG) regions. The first band gap covers optical communication wavelengths. The minimum transmission efficiency of more than 95% and the average channel spacing of 0.98 nm have been obtained for the designed demultiplexer. © 2024 National Institute of Optoelectronics.
