Analog Optical Computing: Toward Sustainable Machine Learning Models and Beyond

Francesca R. Parmigiani, Hitesh Ballani, Grace Brennan, Burcu Canakci et autres

We present a low-cost, room-temperature Analog Optical Computer (AOC) and its applications. Through hardware-applications co-design, AOC leverages the unique speed and parallelism of optics to accelerate machine learning inference and complex optimization problems by up to$100 \times$over conventional digital systems.
