Compact and Low-Loss PCM-based Silicon Photonic MZIs for Photonic Neural Networks (2309.06579v1)

Published 18 Aug 2023 in cs.ET and physics.app-ph

Abstract: We present an optimized Mach-Zehnder Interferometer (MZI) with phase change materials for photonic neural networks (PNNs). With 0.2 dB loss, -38 dB crosstalk, and length of 52 micrometer, the designed MZI significantly improves the scalability and accuracy of PNNs under loss and crosstalk.
