摘要

Abstract

To reduce system complexity and bridge the interface between electronic and photonic circuits

there is a high demand for a non-volatile memory that can be accessed both electrically and optically. However

practical solutions are still lacking when considering the potential for large-scale complementary metal-oxide semiconductor compatible integration. Here

we present an experimental demonstration of a non-volatile photonic-electronic memory based on a 3-dimensional monolithic integrated ferroelectric-silicon ring resonator. We successfully demonstrate programming and erasing the memory using both electrical and optical methods

assisted by optical-to-electrical-to-optical conversion. The memory cell exhibits a high optical extinction ratio of 6.6 dB at a low working voltage of 5 V and an endurance of 4 × 10

cycles. Furthermore

the multi-level storage capability is analyzed in detail

revealing stable performance with a raw bit-error-rate smaller than 5.9 × 10

−2

. This ground-breaking work could be a key technology enabler for future hybrid electronic-photonic systems

targeting a wide range of applications such as photonic interconnect

high-speed data communication

and neuromorphic computing.
