The development of data transmission speed through electronic components has been reaching a bottleneck due to the limited bandwidth and power density, despite new nanofabrication method for advanced microprocessor developed with enormous amount of investment. Accordingly, a new technology with advanced Si nanophotonics has been emerged as a promising candidate not only for the next-generation chip-scale data communication network within data centers, but also for the optical computing which has a higher bandwidth, faster speed, and higher power density than the conventional electronic microprocessor. Recently, we have demonstrated a potential solution to realise highly efficient Si-based nanophotonic integrated circuits, by using photonic crystal cavity to significantly reduce the footprint and enhance the laser performance significantly.
Dr Mingchu Tang obtained his PhD degree on Molecular Beam Epitaxy of III-V compound semiconductors and optoelectronic devices in 2016 and soon after he started his postdoc research associate and promoted to senior research fellow in 2019. His research interests mainly include the monolithic integration of III-V optoelectronic device on Si platform especially edge-emitting and micro/nano cavity lasers. He is now a Lecturer in the Department of Electronic and Electrical Engineering at UCL. He has published more than 80 peer-reviewed journal papers.
