Phase and Amplitude Trimming of Photonic Integrated Circuits Using Phase Change Materials
2022 IEEE Photonics Society Summer Topicals Meeting Series (SUM)(2022)
摘要
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 Sb

, we demonstrate devices with <0.3 dB insertion loss and “active” trimming in both phase and amplitude.
