摘要

通过等频图分析并结合时域有限差分法模拟,在一个与偏振态无关的自准直光子晶体环形谐振腔中,研究发现当环形谐振腔内的光传输距离改变时,横电波(TE)和横磁波(TM)两种偏振态的光在通过环形谐振腔之后的输出将会随之变化并呈现出不同的周期性.通过选择适合的传输距离,实现了TE,TM自准直的情况下同时分束50%的结果,构成了一种基于光子晶体自准直环形谐振腔的全光均分束器.全光均分束器扩大了分束器的运用范围,也会在高密度集成光路中发挥重要的作用.

Abstract

By the equi-frequency contour analysis and the finite-difference time-domain simulation, it is observed that the distance of one lop in a photonic crystal self-collimation ring resonator can cause different periodic outputs of the ring resonator for TE and TM polarizations. Equal intensity polarization-independent beam splitter can be achieved by choosing a suitable propagation distance. It expands the range of application of beam splitter and will play a great role in integrated optical circuits.
