Silicon Non-Volatile Optical Memory and All-Silicon Photonics

We demonstrate a novel silicon non-volatile optical memory fabricated using standard silicon photonics processes. It demonstrates a non-volatile wavelength shift of up to ~ 42 pm, resulting in an optical power difference of ~ 18dB, and supports 26 distinct states. This optical memory can be seamlessly integrated into silicon photonic integrated circuits, providing a straightforward and cost-effective all-silicon photonic solution.
