摘要

非易失性可重写相变材料通过局部调谐波导有效折射率，是光子集成电路加工后修整的理想材料。使用基于Sb2Se3的电可配置移相器，我们演示了插入损耗<0.3 dB和相位和幅度“主动”微调的器件。

Phase and Amplitude Trimming of Photonic Integrated Circuits Using Phase Change Materials

Nonvolatile rewritable phase change materials are ideal for post-fabrication trimming of photonic integrated circuits by locally tuning the waveguide effective index. Using electrically configurable phase shifters based on Sb2Se3, we demonstrate devices with <0.3 dB insertion loss and “active” trimming in both phase and amplitude.
