Ultra-low Crosstalk Multiplexer for Neuromorphic Photonic Data Processing

2022 · Conference on Lasers and Electro-Optics

Neuromorphic architectures aim for powering artificial intelligence algorithms energy efficiently. We fabricate a neuromorphic photonic circuit for matrix vector multiplications using phase change materials and integrate wavelength multiplexers with a crosstalk below -41 dB on-chip.

In-memory photonic dot-product engine with electrically programmable weight banks

2023 · arXiv (Cornell University)

Electronically reprogrammable photonic circuits based on phase-change chalcogenides present an avenue to resolve the von-Neumann bottleneck; however, implementation of such hybrid photonic-electronic processing has not achieved computational success. Here, we achieve this milestone by demonstrating …
