A novel eight-channel demux device based on multicore photonic crystal fiber (PCF) structures that operate in the C-band range (1530⁻1565 nm) has been demonstrated. The PCF demux design is based on replacing some air-hole areas with lithium niobate and silicon nitride materials over the PCF axis alongside with the appropriate optimizations of the PCF structure. The beam propagation method (BPM) combined with Matlab codes was used to model the demux device and optimize the geometrical parameters of the PCF structure. The simulation results showed that the eight-channel demux can be demultiplexing after light propagation of 5 cm with a large bandwidth (4.03⁻4.69 nm) and cross-talk (-16.88 to -15.93 dB). Thus, the proposed device has great potential to be integrated into dense wavelength division multiplexing (DWDM) technology for increasing performances in networking systems.
已展示了一种基于多芯光子晶体光纤（PCF）结构的新型八通道解复用器装置，该装置工作在C波段范围（1530⁻1565纳米）。PCF解复用器的设计基于在PCF轴线上用铌酸锂和氮化硅材料替换一些气孔区域，并对PCF结构进行适当优化。结合Matlab代码的光束传播方法（BPM）用于对解复用器装置进行建模，并优化PCF结构的几何参数。仿真结果表明，八通道解复用器在光传播5厘米后能够进行解复用，具有大带宽（4.03⁻4.69纳米）和串扰（-16.88至-15.93分贝）。因此，所提出的装置具有很大的潜力可集成到密集波分复用（DWDM）技术中，以提高网络系统的性能。
