A Low-Cost Si-based Waveguide Technology Platform for Millimeter-wave/THz Integrated Devices and Systems

Professor Safieddin Safavi-Naeini
RIM Industrial Research Chair University of Waterloo

Millimeter-wave (mmW)/THz range of frequencies have emerged as the best part of electromagnetic spectrum for a rapidly increasing number of applications ranging from security imaging/sensing through opaque shields, to bio-medical/pharmaceutical material characterization and extreme bandwidth communication. However, despite remarkable advances in Nano-scale CMOS and SiGe active device technologies, cost-effective high performance passive devices, system integration, and packaging continue to challenge low-cost/complexity sub-millimeter-wave system developers. This has hindered fast deployment of mmW/THz systems for mass market applications.

In this talk, after a quick review of state-of-the-art in mmW/sub-THz wave guiding and passive technologies, a Si-based waveguide and passive device technology, developed at CIARS (Center for Intelligent Antenna and Radio Systems, University of Waterloo) will be described. The main difficulties with current approaches to high performance (low insertion loss over wide operational frequency band) mmW/THz signal transmission/processing/radiation are discussed. A number of new approaches based on commercially accessible Si technology as well as their practical implementation by the speaker research group will be presented.

Short Biography

Safieddin Safavi-Naeini, received his BSc and MSc from University of Tehran (1975) and MSc and PhD from University of Illinois (USA, 1980), all in electrical engineering. He was an associate professor at U of Tehran until 1996 and has been an adjunct professor in ECE since then. He joined University of Waterloo (Canada) in 1997, where he is now a professor at the Department of Electrical and Computer Engineering. He has 30+ years of research experience in electromagnetics, electromagnetic optics, antenna and wireless systems, RF/microwave technologies, and millimeter-wave/THz devices and systems. He has led several national and international research collaborations, which have resulted in a number of new technologies commercialized by the supporting industries. In recognition of his research achievements, he has been appointed as the NSERC-RIM Industrial Research Chair in integrated radio and photonics since 2004. He is also the director of a newly established University of Waterloo Center for Intelligent Antenna and Radio Systems (CIARS) , an extensive world-class MHz-to-THz multi-lab facility to support far-reaching scientific research in radio- to light-wave technologies.
