Joint Centre for Extreme Photonics (JCEP)


Ebrahim Karimi elected to Royal Society of Canada
We are pleased to announce that JCEP fellow Ebrahim Karimi was elected to the Royal Society of Canada, as a member of the College of New Scholars, Artists and Scientists. Only 50 academics are elected to the College each year across Canada from all disciplines.  Prof. Karimi says “This is a true privilege and honour – Many thanks to all (current and past) members of SQO Group, colleagues and supporters (some are here in JCEP), and friends.  Canada is a place to pursue your dreams.  Also a special thanks to University of Ottawa and The National Research Council Canada (NRC).”
Ebrahim Karimi Wins CAP Herzberg Medal

The Canadian Association of Physicists (CAP) is pleased to announce that the 2020 CAP Herzberg Medal is awarded to Ebrahim Karimi, University of Ottawa, for his innovative leadership in developing structured quantum waves for applications to quantum communication and computation, microscopy and materials science.

Prof. Karimi from the University of Ottawa is a pioneering force in photonics and electron beam optics. He has made ground=breaking contributions to both areas, with results published in the most prestigious physics and other science journals. He developed novel devices that generate structured photonic and electronic waves that have been used in several important applications for quantum communications, microscopy, and materials science. Prof. Karimi’s team successfully employed these devices in quantum communication protocols over the city of Ottawa and through the Ottawa river; in quantum sensing and metrology; as well as in engineering the quantum wave-function of electrons for material characterization in electron microscopy. Furthermore, his team showed that polarization of optical beams possessing tailored structures forms exotic 2 and 3-dimensional topologies, such as polarization Möbius, ribbon strips, knots and framed knots. His achievements also include generating electron vortex beams that found numerous applications in materials science.

Prof. Karimi’s significant contributions to physics have earned him numerous prestigious awards and recognitions. Among those, the Canada Research Chair in Structured Light, the Ontario Early Researcher Award, the University of Ottawa Early Career Researcher of the Year Award in 2019, membership in the College of New Scholars at the Royal Society of Canada and the Global Young Academy, fellowship in the Optical Society, to name a few. His fundamental work attracted significant international attention, leading to invitations to give colloquia all over the world. He played a major leadership role in establishing a new research center, dedicated to quantum optics advancement in Canada.

JCEP is a joint undertaking between the National Research Council (NRC) and the University of Ottawa (uOttawa).  Started in 2019, its goal is to amplify the research efforts of both organizations in the area of photonics.

“Extreme photonics” refers to the two limits of intensity — high and low.  On the low-intensity side, we use intensities so weak that they contain but a single photon, in the realm of quantum optics.  On the high-intensity side, we use femtosecond lasers whose intensities can ionize atoms and molecules, and can generate XUV attosecond pulses, or create pulses in the terahertz frequency range.
