Our modern interconnected society is built upon two foundational technologies; the compute power of silicon CMOS and the capability of photonics for transmitting vast amounts of data in telecommunication networks. The seamless integration of silicon electronics and III-V photonics has been a long-standing goal to merge these two worlds on a single chip. As silicon photonics integrated circuit (PIC) technology matures, there’s renewed interest in combining passive silicon waveguides with other materials in hybrid devices and systems, to add functionality not achievable with silicon alone. In this talk I will cover the work which was done in my former group at IBM research on developing novel epitaxial techniques for the monolithic integration of III-Vs on Si. Notably, I will focus on waveguide coupled high-speed III-V photodetectors and III-V photonic crystal lasers on silicon for on-chip optical communication. I will also discuss our research in the context of new developments at the Paul Scherrer Institute, PSI. In particular investigating active materials beyond III-V and exploring lasing in coupled nanolaser systems.

Kirsten E. Moselund received the M.Sc. Degree in Engineering from the Technical University of Denmark (DTU) in 2003 and the Ph.D. Degree in Microelectronics from EPFL, in 2008. Subsequently, she joined IBM Research Europe - Zurich, where she took on a number of different positions before returning to academia. Lastly, she managed the Materials Integration and Nanoscale Devices group.
Since 2022 full professor of electrical and microengineering in the Faculty of Engineering and Technology at EPFL. She is head of the new Laboratory of Nano and Quantum Technologies (LNQ) at Paul Scherrer Institut (PSI), where among other things she is responsible for the cleanroom and the ETHZ-PSI quantum computing hub.
Throughout her career, she has worked on various topics related to semiconductor devices and technology development, such as low-power electronics, cryogenic electronics, integrated photonics and topological devices. She is author/co-author of more than 100 papers and has filed >30 patents.
