Exceptional points are branch point singularities of self-intersecting Riemann sheets, which can be observed in a non-Hermitian system with complex eigenvalues. In optics, there have been a diversity of intriguing effects based on exceptional points, e.g. loss induced transparency, lasing, and unidirectional reflection. When adiabatically changing the parameters of a system around an exceptional point in parametric space, the initial eigenstate will transfer to another while gaining a geometric phase. Recently, Berini’s group demonstrated mode transfer by dynamically encircling exceptional points in coupled dielectric waveguides at optical telecommunication wavelengths and have shown that encircling a moving exceptional point provides a new scheme to optimize performance, diminish length and insertion loss, while maintaining the topological properties of the operation. These concepts will be further explored in silicon photonics implementations, in particular subwavelength metamaterial waveguides as pioneered by the NRC silicon photonics group, as well as in metasurfaces and nanoplasmonic systems. The technology developed in the collaborative research project would constitute a substantial advance in the field and contribute to making Canada a global leader in emerging quantum photonics sensor technologies.

The Project will focus on the development of coherent quantum imaging techniques for mining applications. Based on nonlinear optical microscopies, the Project will address the shortcomings of current mineralogical sample characterization techniques. The techniques will also be applicable across a range of industrially relevant materials, particularly those that are susceptible to laser-induced damage, such as those containing significant amounts of carbon. To better understand where the advantages of quantum enhanced nonlinear optical microscopy will be of benefit to Canada, the University of Ottawa will work with the NRC-EME team to identify resource streams where improved rapid sample characterization would have the largest benefit. By targeting timely and consequential problems in mining, the Project will lead to the development of new tools for more efficient mining operations with reduced waste and improved yields in Canada
