Abstract

Electro-optical computing systems are promising for future energy-efficient computing, while scalable, dual electrical-optical functionality and low energy-consumption electrical-optical devices are not yet implemented on-chip. In this work, with a tailored design for better heat confinement, we implement scalable phase-change devices with dual electrical-optical functionality. They show ultralow programming energy for both electrical and optical switching in a pico-joule scale, which is orders lower than other integrated electro-optical phase change devices, multilevel switching until 20% contrast, good cyclability, and readout in both electrical and optical domains.
