Our research studies the interaction between light and nanoscale systems such as single atoms, electron spins and nanomechanical structures. Using nanofabrication methods to engineer the optical properties of these systems, it is possible to dramatically enhance light-matter coupling, opening the door to experiments which use light to delicately measure and transmit information describing the dynamics of quantum systems.
Recent results involve fabrication of diamond mechanical resonators whose motion can be controlled by light and used to probe the quantum state of electron spins, demonstration of ultrasenstive optomechanical torque sensors that we have used to detect nanoscale magnetic effects, and design and demonstration of photonic device with ultrahigh nonlinear properties.
This research has applications in the emerging field of quantum information processing, in developing low power optical devices, and creating sensitive and compact environmental sensors.
We are fortunate to have labs at both the University of Calgary and the National Institute for Nanotechnology (NINT) located at the University of Alberta. In Calgary, we work within the Institute for Quantum Science and Technology (IQST) alongside other leading quantum optics research groups. At NINT, we interact with a diverse set of researchers whose expertise spans all areas of nanotechnology, and we have access to some of the most advanced nanofabrication tools in Canada.
