Abstract: Photonic integrated circuits, implemented in silicon, have become a mainstream technology for providing high-speed optical communication links within data centres. Other applications include various sensors (LIDAR, biomedical, environment), optical computing, and quantum information processing.  Perhaps the most ambitious application for integrated photonics is in quantum computing. Photonics can be used for the computation itself (e.g. PsiQuantum, Xanadu), or can be an enabling technology to couple between spin qubits to build scalable hybrid photonic-spin quantum processors (the SFU-UBC SiQL CFI project, Photonic Inc.).  Finally,  photonics can be used for that it does best – optical communications – to build quantum communication links between quantum processors and quantum sensors.  This talk will discuss research to develop the ingredients necessary for these technologies. This includes novel fabrication techniques using electron beam lithography (SiEPICfab consortium), the design of devices such as single photon sources, single photon detectors, and tunable high-Q resonators for spin qubits, and building instrumentation to test these devices and circuits including cryogenic probe stations and cryogenic photonic packaging.

Lukas Chrostowski is a Professor of Electrical and Computer Engineering at the University of British Columbia. Through his research in silicon photonics, optoelectronics, high-speed laser design, fabrication and test, for applications in optical communications, biophotonics, and quantum photonics, he has published more than 300 journal and conference publications. He co-authored the book “Silicon Photonics Design” (Cambridge University Press, 2015).  Dr. Chrostowski was the co-director of the Advanced Materials and Process Engineering Laboratory (AMPEL) Nanofabrication Facility (ANF), 2008-2016.  Dr. Chrostowski was the Program Director of the NSERC CREATE Silicon Electronic-Photonic Integrated Circuits (Si-EPIC) training program in Canada, and has been teaching numerous silicon photonics workshops and courses since 2008, which continue today as the SiEPICfab consortium.  Chrostowski received the Killam Teaching Prize at the University of British Columbia in 2014, IEEE Photonics Society Technical Skills Educator Award in 2021, and IEEE Canada’s J.M Ham Outstanding Engineering Educator Award in 2021.  He was an elected member of the IEEE Photonics Society 2014-2016 Board of Governors.  He was elected to the college of the Royal Society of Canada in 2019. Chrostowski is the Program Director for the NSERC CREATE 2020-2026 Quantum Computing program (Quantum BC), co-leading the Quantum Silicon Photonics design-fabricate-test workshop.
