Microelectronics, Electromagnetics and Photonics
The activities of the microelectronics, electromagnetics and photonics research (MEP) group are directed at design, modelling, and testing of devices and systems for communication systems. The group has a strong focus in the design of high-speed electronics, with three members working in this area.
Current high-speed electronics areas include optical transconductance amplifiers (OTAs), high data-rate modulators, low-temperature ceramics for high-Q materials, and low-cost CMOS for integrated antennas and photonic systems. These activities are competitive internationally, and in many cases are unique in Canada. For example, the work in OTAs is unique within Canada for the high-frequency range that is targeted, and the work on low-temperature ceramics for monolithic 3-D ceramic circuits on ICs is the first in the world.
Two faculty members work primarily in photonic systems. Much of the work is focused on high-speed data transmission systems in the current Internet backbone, and for future systems. Current work includes all-optical signal processing (clock recovery, regeneration, wavelength conversion), electronic signal processing for optical waveform generation and digital coherent receivers, and fiber-to-the-home systems. Work is ongoing to integrate mature optical sensing technology developed for strain measurement into micro-fluidic channels.
Researchers in this group have international reputations: J. C. Cartledge is a Fellow of the IEEE, Fellow of the Optical Society of America (OSA) and holder of a Queen's Research Chair. Y. Antar, one of the cross-appointed faculty, is a Fellow of the IEEE and holder of a Canada Research Chair. The group regularly collaborates with a wide range of national and international companies.
The activities of the group are well supported by local fabrication and measurement capabilities. The Advanced Photonic Systems Laboratory (APSL) at Queen's University, part of the National Microelectronics and Photonics Testing Collaboratory, is directed by a member of this group. This is the premier university facility in Canada for experimental research in fiber-optic communications, and provides some measurement capabilities that are unique in Canada. The group also operates microwave measurement facilities for characterization of electronics and antennas. Fabrication and measurement equipment in the Department of Physics, Engineering Physics and Astronomy enables and complements the research in the group.
