Kiyanoush Goudarzi, Doyoung Kim, Haewook Han

摘要:

基于硅光子学技术的小尺寸、高效率的宽带偏振分束器在光集成电路中具有重要意义。本文采用伴随法的逆设计方法,对TE/TM偏振分束器的关键光学元件进行了设计和仿真。该器件在200 nm的带宽上具有超高的透射效率(TM $_{00}$约96%,TE $_{00}$约93%)和大于16 dB的高消光比。小尺寸(2.2 $\times$ 2.1 $μ$ m $^2$)、宽带宽(200 nm)以及与CMOS工艺制造的兼容性表明该器件符合要求。

英文摘要:

Highly-efficient broadband polarization beam splitters with small footprint and based on silicon photonics technology are of great importance in optical integrated circuits. In this paper, a crucially applicable optical component of a TE/TM polarization beam splitter has been designed and simulated using the inverse design of adjoint method. The mentioned device has ultra-high transmission efficiency (about 96% for TM$_{00}$ and 93% for TE$_{00}$ modes) and high extinction ratio of more than 16 dB over the bandwidth of 200 nm. Small footprint (2.2 $\times$ 2.1 $μ$m$^2$), broad bandwidth (200 nm), and compatibility with CMOS technology fabrication indicate the eligibility of this device.
