All-Silicon Optical Interconnects
We demonstrate the concept of a dense wavelength division multiplexing (DWDM) transceiver (TRx) based on all-Si, Ge-free microring structures, capable of 200 Gb/s/lane Tx and 160 Gb/s/lane Rx. The utilization of all-Si DWDM TRx offers a promising solution for higher data density optical interconnects, featuring simpler and more cost effective SiPh fabrication. It can be readily scaled up to 1.6 Tb/s using DWDM technology.
Non-Volatile Optical Memory
By utilizing the novel photon avalanche-induced trapping effect, we invent a non-volatile Si optical memory with 26 distinct states, robust retention and endurance. This Si avalanche-induced trapping memory (ATM) provides a distinctively cost-efficient and high-reliability route to realize optical data storage in standard SiPh processes. A proposed in-memory computing system achieves image recognition from the MNIST database with an inference accuracy of 94.8% and energy efficiency of 1.64×1013 MAC/J.
Heterogenous Integration
We introduce a silicon photonics platform that maximally harnesses the potential of both the heterogeneous III-V material system and Si, supporting a diverse range of high-performance optoelectronic devices, including lasers, optical amplifiers, modulators, photodetectors, and emerging non-volatile optical memories. This platform delivers a CMOS-compatible, wafer-level integration solution, offering enhanced functionality and expanded application potential.
