Abstract

Integration of chalcogenide phase-change material (PCM) with photonic circuits offers a practical route of introducing nonvolatile optical memories—a key enabling capability for optical neuromorphic computing. The prospect has motivated a surge of research efforts in this field and significant improvements in the performance of PCM-based photonic devices. These advances prompt an important question: what are the ultimate performances that can be achieved in PCM-based photonic devices? Here we address the question by quantitatively analyzing performance bounds of PCM memories on optical loss, crosstalk, energy consumption, and multi-level operation.
