How to realize a silicon-based polarization beam splitter (PBS) with dynamically reconfigurable properties and excellent performance is a vital challenge. Here, we propose a high-performance non-volatile switchable PBS using GST-on-silicon waveguides. Over the C-band, the crosstalk (CT) is lower than ???23.40??dB and polarization extinction ratio (PER) is larger than 21.35??dB for the amorphous GST, while the CT is smaller than ???27.37??dB and PER is greater than 21.37??dB for the crystalline GST.

基于硅基 GST 波导的可切换偏振分束器


如何实现具有动态可重构特性和优异性能的硅基偏振分束器（PBS）是一个至关重要的挑战。在这里，我们提出了一种使用硅上 GST 波导的高性能非易失性可切换 PBS。在C波段，非晶GST的串扰（CT）低于23.40dB，偏振消光比（PER）大于21.35dB，而CT小于27.37dB对于晶体GST，??dB 和PER 大于21.37??dB。
