Prof. Alan Pak Tao LAU, core member of PRI, and PolyU PhD student Xiong WU in collaboration with Prof. Hon Ki TSANG of CUHK developed the World’s fastest Germanium-Silicon(GeSi) on Silicon Photonics Transceiver at 216 Gb/s for Short-Reach Interconnects.
Abstracts
For next generation highly integrated transceivers, silicon photonics (SiP) has attracted widespread interest in using mature CMOS production processes to manufacture high-yield, low-cost photonic integrated circuits (PIC) with the potential for integration with CMOS electronics. SiP now routinely integrate GeSi electroabsorption modulators (EAM) and GeSi waveguide photodiodes which have high responsivity and high bandwidth of over 65 GHz. Their ultra-compact dimensions make it possible for multi-channel transceivers to be realized on a small chip area. In this work, we joined forces with CUHK and combine our expertise in signal processing and device fabrication to demonstrate a world-record 216 Gb/s and 200 Gb/s over 1 km and 1.5 km fiber transmission respectively for GeSi-based modulators.
