Woodpile结构三维光子晶体中的四端口通道下载滤波器

基于三维光子晶体空间完全带隙的特性, 本文在实验上构建了一种由非共面的两个波导和一个立体微腔组成的四端口通道下载滤波器。讨论了球体、正方体、长方体微腔滤波器的选频特性, 以及连续旋转长方体微腔时, 其输出频率的变化。研究结果表明, 无论是对称型还是非对称型微腔, 都可以较好地实现选频。提高微腔的不对称性, 共振输出频率随之发生移动, 说明改变微腔的对称性, 可以有效调节滤波器的选频特性。连续旋转非对称型长方体微腔, 输出频率会随之发生明显的移动,如果引入有效调节机制, 可以产生连续调节输出频率的效果。该研究结果给多端口选择性输出空间滤波器的设计提供了新的思路, 为光学器件集成化的设计提供了重要的理论参考。

Abstract

A compact non-planar four-port channel drop filter was developed experimentally in the three-dimensional Woodpile photonic crystal with a complete band gap. It consisted of two waveguides separated by a defect in different layers of the photonic crystal. The property of frequency selecting of channel drop filter with sphere cavity, cube cavity, cuboids cavity and cuboids cavity rotating was discussed experimentally. The results show that the property of frequency selecting of channel drop filter can be realized whatever the cavity is symmetric or non-symmetric in the Woodpile structure. It indicated the output frequency can be effectually regulated by changing the symmetric of non-planar cavity. For a non-symmetric cavity, the output frequency can be adjusted as the rotation of the cavity. If the effective regulation mechanism is introduced, the output frequency can be adjusted continuously. The results provide a new idea and an important theoretical reference for the design of optical integrated devices.
