摘　　要：低维材料嵌入微腔已经广泛应用于纳米激光器和探测器等。为了实现增益材料和光学微腔之间的有效耦合,需要深入研究嵌埋材料对腔共振模式的影响。本文主要讨论了嵌埋材料的厚度、位置、腔层厚度以及分布式布拉格反射镜的对数对腔供着模式的影响。结果表明,腔共振模式随嵌埋材料位置的不同呈现周期性变化并且在λ/2光程周期内存在最大峰位移。最大峰位移随腔层厚度增加而减小,但与嵌埋材料的厚度成正比。分布式布拉格反射镜的对数不影响腔共振模式。这些结果为光学器件的设计和实验现象的分析提供了指导,并且可以应用于不同波长分布式布拉格反射腔结构。Low-dimensional material embedded cavities have been widely used in nano-lasers and detectors etc.The effects of embedded materials on the cavity resonant mode need to be intensively studied for achieving the ef⁃ficient coupling between the gain material and the cavity.The influences of embedded material thickness and posi⁃tion,cavity layer thickness and the number of distributed Bragg reflector pairs on the cavity resonant mode are dis⁃cussed in this work.Results show that the cavity resonant mode changes periodically with different embedded po⁃sitions and there is a maximum peak shift within a period ofλ/2 optical path.The maximum peak shift decreases with increasing cavity thickness and is proportional to the embedded material thickness.The number of distributed Bragg reflector pairs does not affect the cavity resonant mode.These results provide guidance on the optical de⁃vice design and the analysis of experimental phenomena,which can be applied to different wavelength ranges of distributed Bragg reflector cavity structures.
