Silicon photonics coherent transceiver modules have many technical advantages for optical communication applications with the transmission distance in the range of tens kilometers or longer (such as the metropolitan edge network and the decentralized data center applications). The application demand is expected to increase rapidly and there are already 100-400 Gb/s silicon photonics coherent transceiver products on the market. Some important international standards for 400 Gb/s optical coherent transceiver modules have been finalized and the continuous growth of the future market share can be expected. During this talk, the current development trends of silicon photonics coherent transceivers will be reviewed. I will highlight the important technologies and break throughs that have inspired our own development work at National Yang Ming Chiao Tung University (NYCU), including the various aspects of (1) silicon photonics coherent transmission; (2) silicon photonics active devices; (3) silicon photonics passive devices; (4) silicon photonics coherent transceiver ICs; (5) silicon photonics coherent transceiver packaging; (6) heat dissipation techniques for silicon photonics coherent transceivers; (7) integrated simulation/design platform for silicon photonics & advanced communication applications.
