The development of highly-coherent laser sources through the hybrid integration of III-V gain media and passive silicon photonic low-loss cavities has disparaged the notion that the poor light emission properties of the silicon material will hinder the viability of CMOS-compatible silicon photonics as a photonic platform. Our work in hybrid III-V/silicon lasers have resulted in demonstrated performance metrics (i.e., side-mode suppression ratio, wavelength-tuning, linewidth, relative intensity noise) that would be difficult to achieve amongst solitary III-V lasers. These lasers are expected to play a key role in enabling current and emerging applications such as high-bandwidth optical communications, coherent LIDAR and optical sensing.
Dr. Brian Sia (Member, IEEE, Optica (formerly OSA)) was born in Singapore, in January 1991. He received the B.Eng. degree from Nanyang Technological University, Singapore in 2016. In 2021, received his Ph.D. from Nanyang Technological University, Singapore and was elected as the Valedictorian for the faculty of engineering. During his graduate work, Brian was the First in the world to demonstrate hybrid III-V/silicon lasers operating from 1647 – 1690, 1881 – 1947, 1955 – 1992 nm, motivated by the potential of application-rich wavelength regions in the infrared. Brian has also worked on passive and active silicon photonics. Brian was a visiting researcher at the Tokyo Institute of Technology, Tokyo, Japan and Intel Labs, Santa Clara, USA in 2018 and 2020 respectively. In 2021, through the commercialization of the technology developed during his graduate work.
