摘要

描述了高质量因子Q和小尺寸椭圆截面微腔。本文对椭圆微腔的性能进行了数值研究。我们设计了椭圆微腔来控制偶极体的发射速率，并研究了椭圆度因子对Purcell因子和q因子的影响。我们证明了基于tio2的反射镜的Purcell因子提高了16 × 103，基于zns的反射镜的Purcell因子提高了8 × 103。在1550 nm处的数值研究也表明，椭圆度因子（ε = 0.4）对Purcell和q因子有显著影响。这些好处在短波长的情况下更有说服力。

Investigating the Influence of Ellipticity on the Purcell and Quality Factors in Planar-Elliptical Bragg Mirrors.

High-quality factor Q and elliptical cross-section microcavity of small size are described. We present a numerical investigation of the performance of the elliptical microcavity. We design elliptical microcavities to control the emission rate of dipolar emitters and investigate how the ellipticity factor influences the Purcell and Q-factors. We demonstrate an enhancement of up to 16 × 10³ in the Purcell factor for TiO₂-based mirrors and 8 × 10³ for ZnS-based mirrors. A numerical study at 1550 nm also shows that an ellipticity factor (ε = 0.4) could significantly affect the Purcell and Q-factor. These benefits are expected to be even more persuasive in short wavelengths.
