Centre for Emerging Device Technologies (CEDT)


The Centre for Emerging Device Technologies (CEDT) is an organization that facilitates study of the optical, electrical, mechanical, and biological properties of semiconductors and related materials and promotes the development of technology based on these materials. 

In 1987, faculty members of McMaster University founded the CEDT under its original name, the Centre for Electrophotonic Materials and Devices (CEMD), in order to pool resources, enhance facilities, promote industrial collaboration, and advance research. In 2005 the name of the Centre was changed to CEDT to better reflect the diversified range of research topics in which group members have become increasingly involved. 
Today the Centre is made up of member faculty and graduate students from the Departments of Engineering Physics, Electrical Engineering, Physics, Materials Engineering, Mechanical Engineering, and Chemical Engineering. Six full-time staff operate and maintain equipment for material growth, analysis, and processing, located in four laboratory facilities. We develop lasers, MEMS, detectors, waveguide devices, and much more. Industrial collaborations take place frequently and new initiatives are always welcome.



As an organization, the CEDT amounts to a collective of people and pooled resources. Faculty from various departments who have an interest in the resources operated by the CEDT pay on a fee for service basis to use CEDT equipment facilities.. As members associated with the CEDT, the faculty and their students are granted access to the CEDT's analytical equipment, and pay special rates for the use of processing and growth facilities. 

The CEDT operates as a collective of shared resources. The people that keep the Centre running include faculty from a number of universities, their students and research associates, full-time CEDT technical staff, as well as industrial collaborators.

The focus of the CEDT has been on photonics and optical materials and devices, but the approaches and applications are extremely diverse. Over the last 4 years the number of major university users in the CEDT has grown rapidly from 29 to 59. The growth in major users had been due to 7 newly hired faculty members. The presence of the CEDT was a strong incentive in the hiring of these new faculty since their research programs rely heavily on the materials growth, device processing and characterizations facilities in the CEDT, which would be difficult to replicate in another Canadian University.

You will find that the research interests span a diverse area. The research summaries of the individual faculty members will point out the many interactions, breadth and depth of the research activity of members associated with the CEDT.

We also have many other faculty members from various outside universities and companies that are associated with our Centre.
