ABSTRACT

Dual optical and acoustic unidirectional transmission in two-dimensional phoxonic crystal rectangular defect connected by two mutually perpendicular waveguides is theoretically achieved. The unidirectional filtering for both optical and acoustic waves is designed by altering the phoxonic crystal waveguides and cavity to obtain the modes’ match and mismatch via the finite element method. This kind of devices has the abilities of mode convertor, wavelength filtering and unidirectional propagation for both the optical and acoustic wave, and maybe potentially applied in simultaneously manipulating light and sound.

具有矩形缺陷的二维光子晶体双光学和声波单向滤波的理论研究

摘要

理论上，在通过两个相互垂直的波导连接的二维光子晶体矩形缺陷中，实现了光和声的单向双向传输。通过改变光子晶体的波导和腔来设计光波和声波的单向滤波，以通过有限元方法获得模式的匹配和失配。这种设备具有对光波和声波进行模式转换，波长滤波和单向传播的能力，并且可能潜在地应用于同时操纵光和声。
