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 …

Performance Enhancement via Synaptic Plasticity in an Integrated Photonic Recurrent Neural Network with Phase-Change Materials
2023
Synaptic plasticity, i.e. the ability of synaptic connections to strengthen or weaken depending on their input, is a fundamental component of learning and memory in biological neural networks [1]. This property allows the network parameters …
