摘要: 为了设计一种基于正方晶格光子晶体波导的三端口解波分复用器,利用光子晶体的光子带隙特性和光在光子晶体慢光波导中的传输特性,并采用平面波展开法及时域有限差分法对解波分复用器的特性进行了理论分析,数值计算了解复用器的空间和光谱分布特性。结果表明,调整波导中与波导紧邻的第1排柱子的位置,使三部分波导中传输的慢光频率发生改变,通过合理的结构设计,利用慢光模式传输的特点将不同频率的光从不同的输出端输出,可实现解复用的目的。

Abstract: In order to design three-port wavelength-division demultiplexer based on square lattice photonic crystal waveguide, wavelength-division demultiplexer was analyzed theoretically by using the characteristics of photonic band gap of photonic crystal and the transmission characteristics of slow light mode in photonic crystal, by using plane wave expansion method and finite difference time domain method. The spectral and spatial characteristics of wavelength-division demultiplexer were calculated numerically. The results show that adjusting the position of the column at the first row adjacent to the waveguide will change the frequency of slow light transmitted in three parts of waveguide. Based on the transmission characteristics of slow light, provided a reasonable structure design, the light beams at different frequencies can output from different output terminals, and the purpose of demultiplexing can be achieved.
