Abstract
Si photonics has been developed to enable the next generation tele- and data-communications for its high performance, making use of the mature silicon CMOS technologies. It is also fueling various applications such as imaging, sensing, spectroscopy, quantum science and optical metrology. To efficiently couple light between active and passive components for Si photonics, we developed a novel lateral aspect ratio trapping (LART) technology to grow lasers and high-speed photodetectors on patterned commercial SOI substrates for integrated Si photonics. Multimode and single-mode lasing from lateral quantum wells (QWs) as the gain media using LART have been achieved in the 1433 -1630 nm band with varying dimensions of micro-ring lasers. High-performance PDs coupled to Si tapers were also constructed on the monolithic InP/SOI platform with laterally grown p-i-n structures and show open eye diagram exceeding 100 Gb/s. The talk will introduce Si photonics and the motivation of our research for future electronic/photonic integration on the silicon platform.
