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.
