Distributed sensing is an advanced technology that enables real-time monitoring of variations along the entire length of a waveguide, and offers the possibility of sensing from a long distance. In the optics domain, distributed sensing based on optical fibers has been successfully demonstrated. However, the realization of distributed sensing in the terahertz domain is still […]

Optical vortices have recently attracted great interest in many fields of scientific and technologi-cal research. The proposed project aims to experimentally verify the rotational Doppler shift in the nonlinear optical regime using optical vortices. The frequency shift sensed through optical vortices in the nonlinear interaction is expected to be proportional to the order of the […]

The rotational Doppler shift in the nonlinear optical process will improve the precision and resolution of the detection of the dynamics of an object, particularly the resolution of its rotational motion. The project aims at the design, realization and study of rotational Doppler shift based on the nonlinear interaction specifically tailored for the backward-wave phase […]

The intern will work on building power transformers’ aging models based on reliability theories and actual field test data collected using optic fiber based health monitoring technologies. This is part of a novel solution to handle the accident prevention and maintenance for major power and grid equipment. The novelty lies in that the model verification […]

The proposed research aims to develop a novel fiber optic based technology for the monitoring and detection of defaults in power transformers, which could lead to an in-service failure and power outages. The partner company has developed a sensor that is sensitive to vibration and moisture. Also, small electrical sparks, known as partial discharges, in […]

Two out of five Canadians are expected to develop cancer and one out of four Canadians is expected to die from cancer. For treatment of Melanoma, a dangerous skin cancer, plasmonic photo-thermal therapy is applied for precisely localized plasmonic heating of gold nanoparticles to kill cancer. One of the major challenges in heating applications involves […]

A partial discharge is a localized spark that bridges a small portion of the insulation between two conducting electrodes under high voltage. The lifetime of high voltage electronic devices is often determined by the ability of the insulation material to withstand partial discharges, which start within gas voids in solid polymer insulation. A typical monitoring […]
