摘要

A new optical in-memory computing system based on an array of vertical-cavity surface-emitting lasers (VCSELs) has the potential to circumvent the Von Neumann bottleneck. The high modulation speed of the lasers in the array allows for fast computing and their high efficiency can enable edge computing in autonomous vehicles and drones. This efficient, highly scalable system was demonstrated to perform 900 million convolutions per second with 98% computing accuracy.
