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.
